– June 22, 1953 –
While collecting subscription money for the Brooklyn Eagle newspaper, 14-year-old Jimmy Bozart was handed a nickel that felt strangely light and hollow. When he accidentally dropped the coin on the ground, it split cleanly in two, revealing a microscopic piece of film hidden inside a precision-machined cavity. After Jimmy showed the bizarre object to a friend, the friend’s father—a New York City police detective—recognized the threat and alerted the FBI, kicking off one of the most intense counterintelligence investigations of the Cold War.
The microfilm contained 207 columns of five-digit numbers that completely baffled the military’s top codebreakers for nearly four years. The breakthrough only came when a high-ranking KGB operative named Reino Häyhänen defected to the West and handed over the cipher keys, revealing that the numbers were secret messages directly from Moscow. This accidental discovery of a single hollow nickel ultimately led to the arrest of Soviet master spy Rudolf Abel, an event later immortalized in the film Bridge of Spies.
