The Benjamin K. Miller Collection is a unique collection of stamps and other philatelic materials donated to The New York Public Library in 1925 by Milwaukee attorney Benjamin Kurtz Miller (1857–1928).[1][2][3] This collection has been considered the first complete collection of U.S. stamps ever assembled.[1] His collection is known as the "crown jewels" of U.S. stamp collecting for its rare holdings, depth, and variety.[1] Miller's collection was not complete, missing some stamps then listed by Scott.[4]
