The first $10 notes issued by the U.S. federal government are Demand Notes, featuring President Abraham Lincoln’s portrait, fine-line engraving, and intricate geometric lathe patterns. Each Demand Note was immediately redeemable in gold or silver “upon demand” at seven specific banks around the nation. The Treasury issued Demand Notes in 1861 and 1862.
