I have a dollar bill that was autographed by Neil Armstrong, Bob Hope, and Les Browne (Bob's band leader) in December 1969 when they were on the U.S.O. Christmas tour in Vietnam. I imagine it's a "one-of-a-kind".
Any idea what it might be worth?
it needs some kind of COA or proof that they are real. Go to ebay and search signatures of your guys.
