Hitler's Golden Gun
This golden 7.65mm Walther PP was likely never holstered, never mind fired, by history’s most loathsome leader. But undeniably belonging to “A.H.”, it sold for $114,000 at a 1987 auction to an anonymous bidder. It has since quietly changed hands several times, and would likely fetch millions today.
Supposedly gifted to Hitler on his 50th birthday in 1939 by the Walther family, the gun probably remained more of a prized showpiece than a protective accessory. Many historians once believed though — and some still argue — that Hitler used it to commit suicide in his bunker as World War II waned.
The more accepted story says an American soldier looted this treasure during a small splinter mission to capture the Fuhrer just months before his death. Upon infiltrating Hitler’s apartment in April of 1945, the ivory-gripped gun became one of many things the mercenaries secured from his desk drawers. As for the dictator himself, he was miles away in a Berlin bunker, preparing for his suicide.
