An authentic Abraham Lincoln signature is one of the crown jewels of American autograph collecting. He signed as president and as a lawyer, so documents exist, but genuine material is scarce, expensive, and surrounded by facsimiles, secretarial signatures, and outright forgeries.
At Lincoln's price level, authentication and provenance are everything. This is a signature where you work with specialist dealers and auction houses, not open marketplaces, and where every detail of paper, ink, and history matters.
Lincoln most often signed 'A. Lincoln' on documents and correspondence, with a distinctive, economical hand. Full 'Abraham Lincoln' signatures are rarer and more valuable. His signature is well studied, and genuine examples sit on period-correct paper with period iron-gall or similar ink.
