If you’re holding a small, sepia-toned card with "A. Lincoln" scrawled across the bottom, you might be looking at a fortune. Or you might be looking at a $10 souvenir from a museum gift shop. Honestly, the difference between a genuine abraham lincoln signed photograph and a clever fake is often just a few microscopic ink bubbles.
Collecting Lincoln isn't like collecting modern sports cards. It’s gritty. It’s expensive. It’s a world where a single 2x4-inch piece of paper can fetch more than a suburban house. Just recently, in early 2026, the market has seen a surge in interest as high-end collectors scramble for "fresh-to-market" pieces.
But here’s the thing: most of what people think they know about Lincoln’s signature is kind of wrong.
The Secret "Bouncy" Signature
Lincoln didn’t just write his name. He "stepped" it.
If you look at a verified, authentic autograph, you’ll notice it isn’t flat. It doesn't sit on a straight line. Experts like those at University Archives often point out that his signature actually moves upward in three distinct planes. He starts the "A," places a dot (sometimes two), then loops into the "L" of Lincoln on a slightly higher level. By the time he gets to the "n" at the end, he’s stepped up again.
It’s bouncy.

If the signature you're looking at is perfectly horizontal—like someone used a ruler—it’s probably a fake. Forgers like the infamous Charles Cosey were brilliant at mimicking the letter shapes, but they almost always failed the "staircase" test. They couldn't help but write in a straight line.
What is a CDV, Anyway?
In the 1860s, people didn't have Instagram. They had Cartes-de-Visite (CDV).
Basically, these were the "calling cards" of the Civil War era. They were small albumen prints mounted on stiff cardstock. Lincoln was actually one of the first "media" presidents who understood the power of his own image. He sat for photographers like Alexander Gardner and Mathew Brady constantly.
The Gardner Sitting
On August 9, 1863, just a month after the carnage at Gettysburg, Lincoln went to Gardner’s studio. He was in "very good spirits," according to his secretary John Hay. He sat at a marble-topped table, holding his glasses and a newspaper.
Only a handful of these specific Gardner portraits were ever signed by Lincoln. One of these gems, authenticated by PSA/DNA, can easily command over $100,000 at auction today. Why? Because Lincoln didn't just sign things for fun. Most signed photos were given as gifts to close friends, like the Speeds, or sold at "Sanitary Fairs" to raise money for wounded Union soldiers.

How to Spot a Fake (Without Being an Expert)
You’ve got to be a bit of a detective here. First off, Lincoln almost never signed as "Abraham." If you see a full first name or—heaven forbid—"Abe," run the other way. He was a formal man. "A. Lincoln" was his go-to.
Next, get a magnifying glass. Seriously.
- The Ink "Tunnel": Real fountain pen ink from the 1860s has texture. As the metal nib moved across the paper, it would actually "plow" through the wet ink, creating tiny bridges and tunnels you can see under 10x magnification.
- The Halo Effect: Old ink was often made with iron gall. Over 160 years, that ink oxidizes. It turns a rusty, dark brown and sometimes leaves a faint "halo" or yellowing around the letters as the acid eats into the paper.
- The Stamp Trap: Lincoln actually used a signature stamp for some routine documents. If the ink looks perfectly flat and has "squeezed" edges (where the ink was pushed to the sides of the rubber stamp), it’s not a hand-signed piece.
The 2026 Market Reality
What is an abraham lincoln signed photograph actually worth right now?
It depends on the "pose." A common CDV of Lincoln in his later years might start at $50,000 if the signature is clean. But if it’s a rare pose—like the 1864 image of Lincoln with his son Tad—the price sky-rockets. One of those recently pulled in over $135,000.
Provenance is everything. If the photo has a letter from a 19th-century soldier's family or a record from a famous collection like Forbes, the value doubles. Without a "story," you're just buying a piece of paper that might be real.

Common Pitfalls
- Parchment Paper: If the paper feels thick, crinkly, and looks "antique" (like a treasure map), it’s almost certainly a mid-20th-century reproduction. Real Civil War paper was thin, often had "laid" lines (a grid pattern from the drying rack), and felt like high-quality linen.
- Ballpoint Ink: This sounds stupid, but people miss it. If the signature has a blue tint or looks like it was written with a modern rollerball, it’s a fake. Ballpoints didn't exist in 1865.
Your Next Steps
If you think you've found the "holy grail" in your attic, don't touch the signature. Oil from your fingers can degrade the ink.
First, take high-resolution photos of the front and back. Look for any photographer's marks (like "Gardner" or "Brady") on the bottom or the reverse side. Then, contact a reputable auction house like Heritage, RR Auction, or University Archives for a preliminary digital review.
Most authenticators charge a fee—anywhere from $100 to $400—but it’s worth it. You don't want to be the person who sells a $100,000 treasure for fifty bucks at a garage sale because you didn't check for the "three-step" signature.
Keep it out of the sun. UV light is the literal enemy of 19th-century ink. If you’re going to display it, use museum-grade UV glass. Honestly, just keeping it in a dark, climate-controlled safe is the best way to ensure that "A. Lincoln" stays bold for another hundred years.
Actionable Insight: Before paying for professional authentication, use a 10x jeweler’s loupe to check for "ink pooling" at the ends of strokes. If the ink looks like a series of tiny dots (pixelation), it's a modern print. If it looks like a solid, dried river with "plow marks" from a nib, you should definitely proceed with a formal appraisal.
