The Brooklyn newsboy
As seen in the film, Soviet agent Rudolf Ivanovich Abel received coded messages from his KGB handlers that were hidden inside a hollow U.S. nickel. The FBI first became aware of Abel's activities in 1953, when a Soviet agent mistakenly used one of the hollow nickels to buy a newspaper. The Brooklyn newsboy who had received the nickel thought it felt too light. He dropped the nickel on the sidewalk, and it popped open, revealing a piece of microfilm with a coded message inside. But FBI cryptologists were unable to crack the code until 1957, when a KGB defector, Reino Häyhänen, gave them the key to deciphering the code, and also gave up Rudolph Abel. The "Hollow Nickel Case" was also dramatized in FBI slår till (1959), starring James Stewart.
Really cool story. He actually felt that the coin was too light? That is very impressive, I guess.
And a Soviet agent who mistakenly use a top secret coin.. Sounds sloppy.
