It Was Created to Fight Counterfeit Money

The modern image of the United States Secret Service is inseparable from presidential protection: dark suits, motorcades, advance teams, secure perimeters, and agents surrounding the president. That was not the agency Abraham Lincoln’s generation created, because when the Secret Service formally began operations on July 5, 1865, its original job was to defend something else entirely—the credibility of American money.

Lincoln had been dead for nearly three months. John Wilkes Booth had already been killed, the federal government was prosecuting the assassination conspirators, and the new agency was placed inside the Treasury Department rather than organized as a presidential guard force. The enemy it was sent after was the counterfeiter, because the Civil War had produced a new national currency at the same time that forged versions of that currency were spreading through the country.

The images above show the monetary battlefield the early Secret Service entered: a Civil War-era federal note, Robert C. Naramore’s photographic bank-note detector, and an earlier commercial counterfeit detector used by merchants trying to decide whether the paper handed across a counter was actually worth what it claimed. Long before Secret Service agents were associated with protecting a human body, their work centered on protecting trust in a piece of paper.

The Civil War Changed What American Money Was

Before the Civil War, ordinary Americans lived with a bewildering monetary system. State-chartered banks issued their own bank notes, individual notes could circulate far from the institution printed on their face, failed banks left worthless paper behind, and merchants relied on bank-note reporters and counterfeit detectors to decide which bills could safely be accepted.

That older system created opportunities for counterfeiters because verification was difficult. A merchant in Indiana might receive a bill supposedly issued by a bank hundreds of miles away, and deciding whether it was genuine could require familiarity with engraving, signatures, vignettes, paper, serial numbers, bank solvency, and the constantly changing lists of known forgeries.

The Civil War forced the federal government to change that landscape dramatically. Lincoln’s Treasury created greenbacks, expanded federal borrowing, introduced new taxation, established the Bureau of Engraving and Printing, and developed the National Banking System as the Union attempted to finance a war whose costs were unlike anything the federal government had previously encountered. Treasury history records that the Bureau of Engraving and Printing emerged during the war to produce the government’s new currency, while the national banking system sought to create a more uniform financial structure.

That transformation appears throughout The Lincoln Log. The manuscript treats the Legal Tender Acts, national banking, federal bonds, land policy, rail expansion, military administration, and enlarged federal enforcement as parts of a broader wartime expansion of national capacity rather than isolated policy changes.

A stronger national currency solved one problem while creating another. Once federal paper became increasingly important to commerce and government finance, successfully forging that paper threatened not simply an individual merchant or distant local bank but the federal government’s own claim to define legitimate money.

Counterfeiting Was Big Enough to Become a Federal Security Problem

The Secret Service’s own historical material describes counterfeiting immediately after the Civil War as rampant, with agency sources estimating that perhaps as much as 30 percent of circulating currency was counterfeit; older agency reports have sometimes given even higher estimates, which shows that the exact percentage is uncertain even within official histories. What is not uncertain is the institutional response: the government considered the problem severe enough to create a specialized federal investigative organization devoted to suppressing it.

This is easy to underestimate from the perspective of modern currency. Today a counterfeit bill feels like a fraudulent imitation of an already stable national money system, but nineteenth-century counterfeiters operated inside a culture in which Americans had spent decades judging competing paper claims and learning that the appearance of legitimacy could itself make money travel.

A good counterfeiter therefore needed more than a crude printing press. Successful operations depended on engravers, plates, paper, inks, distributors, passers, aliases, merchants willing not to ask too many questions, transportation routes, saloons, hotels, prisons, and people who could convert fraudulent paper into real goods before anyone recognized what had happened.

The Lincoln Log emphasizes exactly that point when discussing the early Secret Service. Its agents had to understand engraving, printing, passing, distribution, aliases, saloon contacts, transportation routes, and the difference between the person who passed a counterfeit bill and the technician who produced the plate from which it came.

That made counterfeiting less like a solitary act of forgery and more like an underground industry.

Lincoln and the Strange Timing of the Secret Service

The Secret Service’s own historical publications state that Lincoln approved the creation of the organization on April 14, 1865—the day he was assassinated. The agency itself was formally established within the Treasury Department on July 5, 1865, under Lincoln’s successor, Andrew Johnson, with Treasury Secretary Hugh McCulloch overseeing the new organization.

That timing has produced one of the great historical ironies attached to the Secret Service. Lincoln approved an agency whose modern descendants are famous for keeping presidents alive, but the organization contemplated in 1865 was not intended to save him from an assassin at Ford’s Theatre because presidential protection was not its assigned mission.

Full-time presidential protection came much later. The Secret Service’s current strategic history dates that permanent responsibility to 1901, after the assassinations of Lincoln, James Garfield, and William McKinley had made the weakness of presidential security increasingly difficult to ignore.

The agency’s origin therefore belongs first to the history of money.

That fact changes how the Secret Service fits into the Lincoln story.

William P. Wood and the First Federal Counterfeit Hunters

The first chief of the new Secret Service was William P. Wood, a Civil War-era federal official who had previously been associated with Washington’s Old Capitol Prison. Secret Service historical materials say that when the service began on July 5, 1865, it had more than twenty operatives distributed among eleven offices across the country.

Wood’s organization did not look like the Secret Service of modern movies. Its operatives had to enter a criminal world in which counterfeit production and distribution were often embedded in otherwise ordinary businesses, social circles, saloons, transportation networks, and local communities.

Even the familiar badge came later. The Secret Service says its historical records do not mention agents obtaining optional badges until Hiram C. Whitley’s tenure beginning in 1869, while the first standardized agency badge appeared in 1873 and the recognizable “Service Star” design followed in 1875.

The early agent’s main advantage therefore was not a famous emblem of federal authority. It was knowledge.

He had to know who could engrave a plate, who supplied suspicious paper, where forged money entered circulation, which saloon connected one passer to another, and which supposed small-time criminal might lead investigators to the production source.

The agency’s own modern investigative strategy describes the original philosophy plainly: infiltrate counterfeit organizations, arrest important participants, and thereby strengthen public confidence in the American dollar.

That mission brought federal investigators directly into the same shadow economy that The Lincoln Log follows across the Midwest.

Why an Engraver Could Be Worth More Than a Gang of Passers

The distinction between making counterfeit money and merely passing it is essential to understanding the strangest later collision between Lincoln and the Secret Service. A passer could take forged notes into circulation, but a skilled engraver could create the physical instrument that made an entire network productive.

An engraver could imitate the visual authority of the state. Fine lettering, portraits, intricate borders, seals, ornamental work, and mechanical precision helped convince people that a piece of paper represented real value, which meant the person capable of reproducing those features occupied a highly specialized position inside the criminal economy.

The manuscript describes such a technician as a production center rather than simply another criminal participant. Removing a passer interrupted circulation, while removing an engraver could damage the whole production process.

That distinction becomes crucial when Benjamin Boyd enters the story.

Boyd was an engraver associated with the Chicago counterfeiting world, and his imprisonment at Joliet in the 1870s created a problem for men who depended on his skill. Their proposed solution brought the Secret Service, counterfeit money, and Abraham Lincoln’s physical body together in one almost unbelievable operation.

Eleven Years After the Assassination, the Secret Service Met Lincoln Again

On November 7, 1876, counterfeiters entered Abraham Lincoln’s tomb in Springfield and attempted to remove his coffin. Their plan was to hide the body in the Indiana Dunes and use the president’s remains as leverage to demand money and the release of Benjamin Boyd.

The federal agent directing the response was Secret Service operative Patrick D. Tyrrell, and an informant named Lewis Swegles had penetrated the plot. Swegles went into the tomb with Terrence Mullen and Jack Hughes while federal officers waited nearby, giving the government an observer inside the crime itself.

This was therefore not the Secret Service performing presidential protection in the modern sense. Lincoln had been dead for eleven years, and the agency entered the case because counterfeiters were trying to trade the dead president for an imprisoned member of their own monetary underworld.

That connection is one of the reasons the tomb robbery sits so naturally inside The Lincoln Log. The manuscript describes the attempted theft as a moment when Lincoln’s body, the counterfeit economy, and the developing federal intelligence state occupy the same scene.

The government that had been created to suppress false money was suddenly guarding Abraham Lincoln’s coffin from the men who made false money.

The Lincoln Connection Was Monetary Before It Was Protective

There is a deeper historical irony here. Lincoln’s administration had presided over the creation of a stronger national monetary architecture, and the Secret Service emerged from the necessity of defending that architecture against imitation.

The Lincoln Log frames that relationship very directly. Lincoln’s administration remade what the manuscript calls the fiscal body of the United States through greenbacks, national banking, bonds, Treasury systems, wartime contracting, military finance, and federal claims over paper; the president whose body counterfeiters later tried to ransom had helped construct the monetary system that turned their trade into a specifically federal enemy.

That does not mean Lincoln personally designed every part of the national banking system or ran federal anti-counterfeiting operations. It means his administration presided over a wartime centralization in which national money became increasingly important to the state’s ability to function.

Counterfeiters attacked the appearance of that authority.

They created paper that claimed to belong to the official system while actually belonging to the underground economy.

The Secret Service existed to determine which was which.

A Counterfeit Detector Was a Trust Machine

One of the most revealing artifacts from the period is not a pistol or badge but a counterfeit detector. Merchants and bankers bought publications containing descriptions or images of legitimate and fraudulent notes because ordinary commerce required constant judgment about whether paper could be trusted.

Robert C. Naramore’s 1866 photographic United States Treasury and National Bank Note Detector reproduced images of federal and national bank notes so that users could compare suspicious currency with legitimate designs. The Library Company of Philadelphia describes it as an early attempt to use photography itself as an anti-counterfeiting technology.

That object captures the central problem beautifully. Money worked because strangers agreed that a printed object carried value, while counterfeiting worked by producing another printed object convincing enough to borrow that agreement.

The state therefore needed its own specialists in appearances.

A Secret Service agent was not merely chasing thieves. He was protecting the boundary between authentic and counterfeit authority.

Why the Secret Service Had to Learn the Underworld

The early Service could not suppress counterfeiting simply by waiting for shopkeepers to report suspicious bills. By the time a forged note reached a merchant, the person passing it might be several layers removed from the engraver, printer, distributor, or organizer who produced the operation.

That meant investigators had to move backward through networks.

The Secret Service’s own modern history describes infiltration as part of its investigative philosophy from the beginning. Agents needed criminal contacts and informants precisely because the most important participants were often insulated from the street-level act that made the crime visible.

The Lincoln Log makes the same point through Lewis Swegles in the 1876 tomb plot. Swegles could enter the conspiracy because the criminals believed he belonged close enough to their world to be trusted, while his hidden relationship with Tyrrell allowed federal knowledge to travel inside the operation before officers physically entered the tomb.

That method—using the underworld’s own relationships to penetrate it—would become a recurring feature of federal investigative work.

The Secret Service learned intelligence practice by fighting money crime.

The State and the Counterfeiter Were Fighting Over the Same Thing

At the deepest level, both sides were fighting over confidence. The federal government needed people to accept that its currency represented real legal and economic value, while counterfeiters needed people to accept that their imitation represented the same thing for long enough to complete a transaction.

The counterfeit bill therefore challenged more than a printing process.

It challenged authority.

The Secret Service’s current descriptions of its historical mission still emphasize protecting the stability and integrity of the country’s financial system, and the agency’s modern duties continue to combine physical protection with safeguarding financial infrastructure.

That continuity makes the original mission easier to understand. The Service was created because a government trying to build a national monetary system could not allow private criminal networks to manufacture convincing substitutes for its own promises.

In a country becoming more dependent on paper, the ability to authenticate paper became a form of power.

The Agency That Didn’t Protect Lincoln Protected His Body

The great irony becomes complete in 1876. The Secret Service did not exist as a presidential protection force when Booth walked into Ford’s Theatre, but eleven years later its anti-counterfeiting agents helped protect the dead president from counterfeiters.

That sequence connects two Lincoln stories that are usually kept in separate historical boxes. One is the Civil War creation of national currency and federal fiscal power; the other is the bizarre attempt to steal Lincoln’s remains from Oak Ridge Cemetery.

The Lincoln Log brings them together because the tomb plot reveals what the two histories shared. Counterfeit money, an imprisoned engraver, a federal intelligence agent, an informant, Chicago criminal networks, the Indiana Dunes, and Abraham Lincoln’s corpse all became parts of the same documented operation.

Nothing about that requires claiming that the 1876 counterfeiters participated in Lincoln’s assassination. The significance lies in what had survived after the assassination: the money conflict, the criminal networks, the growing investigative state, and the continued political value of Lincoln’s physical body.

From Greenbacks to Presidential Protection

The Secret Service eventually acquired the mission everyone now associates with its name. After Lincoln’s assassination in 1865, Garfield’s in 1881, and McKinley’s in 1901, full-time presidential protection was assigned to the Secret Service beginning in 1901.

By then the agency had spent more than three decades learning how to identify threats through networks rather than merely reacting to visible crimes. Its investigators had experience with informants, aliases, surveillance, forged documents, criminal associations, transportation routes, and conspiracies organized so that the person committing the obvious offense might not be the person directing the larger operation.

Those skills transferred naturally into protective intelligence.

That later evolution can obscure the original logic of the agency, but recovering it makes the Secret Service much more interesting. It did not begin because the federal government decided presidents required bodyguards; it began because the government decided that national money required detectives.

Why This Matters to The Lincoln Log

The Lincoln Log: The Machinery Behind the Lincoln Assassination treats Lincoln’s death as occurring inside a larger nineteenth-century world of war finance, national banking, counterfeiting, railroad expansion, theater networks, courts, fraternal systems, Maryland routes, and emerging federal security. The manuscript explicitly identifies the National Banking Acts, Legal Tender Acts, creation of the Secret Service, Ford’s Theatre, Booth’s escape, Benjamin Boyd, and the 1876 tomb robbery as documented pieces of that larger environment.

The Secret Service provides one of the cleanest ways to see that environment change over time. Lincoln’s government expanded national paper money during the war; counterfeiters adapted to the new money; the Treasury created an investigative force to suppress them; that force penetrated the underworld; and eleven years after Lincoln’s death, those investigators found themselves defending his coffin from men trying to exchange the president’s body for a counterfeit engraver.

The sequence sounds too neatly symbolic to be real, yet its central events are documented history. The symbolism comes afterward because the historical machinery had already assembled itself.

The Secret Service did not save Abraham Lincoln at Ford’s Theatre. It was not created for that purpose, and its protective mission belonged to a later generation.

Its first Lincoln story was about money.

Its second involved his grave.

Only later did the agency become responsible for keeping future presidents from sharing his fate.

The Lincoln Log: The Machinery Behind the Lincoln Assassination follows that transition from wartime money and shadow finance into the federal investigative state that emerged after the war. The book is available here: The Lincoln Log on Amazon.
