Series 1963 one-dollar bill, signed on the portrait side blue ballpoint and red felt tip by the full Apollo 1 crew: “Gus Grissom,” “Roger B. Chaffee,” and “Edward H. White II.” The banknote is also signed by original backup pilot Rusty Schweickart (who starts his signature in ballpoint and finishes in felt tip), and one other unidentified signer. In very good to fine condition, with expected wear and creasing, and the first half of Schweickart's signature light but legible. Encapsulated in a PSA/DNA authentication holder and accompanied by a full letter of authenticity from Zarelli Space Authentication.
