Ambrose Lincoln (1917–1989) was a Navajo silversmith working in multiple styles: stamp and file work, set stones, some channel inlay, leaf and appliqué. He was an instructor at the Santa Fe Indian School and worked for C. G. Wallace, Kelsey Indian Trading Company, and Three Hogans.
Ambrose Lincoln's mark — the letter A inside a keystone or broken arrow point — has been the subject of a documented attribution error. Earlier editions of the Hougart hallmark reference and related literature cited Lincoln and Ambrose Roanhorse as possibly the same person. This confusion was corrected: according to an interview with Roger Skeet Jr., Lincoln and Roanhorse were contemporaries, both known to Skeet and to Skeet's father, and were definitively two different silversmiths.
The T.Skies directory documents Ambrose Roanhorse's own page, where the mix-up is documented from Roanhorse's side. Lincoln's A-in-keystone mark is his own, not a shared or confused hallmark.
