TheHollow Nickel Case (or theHollow Coin) was theFBI investigation that grew out of the discovery of a container disguised as aU.S. coin and containing a coded message, eventually found to concern theespionage activities ofWilliam August Fisher (a.k.a. Rudolf Ivanovich Abel) on behalf of theSoviet Union.


On June 22, 1953, Jimmy Bozart,[1] a fourteen-year-old newspaper boy collecting for theBrooklyn Eagle, at an apartment building at 3403 Foster Avenue in theNew York Cityborough ofBrooklyn, was paid with anickel (U.S. five-cent piece) that felt too light to him. When he dropped it on the ground, it popped open, revealing that it containedmicrofilm. The microfilm contained a series of numbers. He told the daughter of aNew York City Police Department officer, and that officer told a detective who, in two days, told anFBI agent about the strange nickel.[2]
After agent Louis Hahn of the FBI obtained the nickel and the microfilm, the agency tried to find out where the nickel had come from and what the numbers meant. The coin had a 1948-datedobverse with the usual copper-nickel composition, but the reverse was minted sometime between October 1942 and the end of 1945, based on thecopper-silver alloys used during this period (nickel was needed for thewar effort). On the microfilm, there were five digits together in each number, 21 sets of five in seven columns and another 20 sets in three columns, making a total of 207 sets of five digits. There was no key for the numbers. The FBI tried for nearly four years to find the origin of the nickel and the meaning of the numbers.[2]
It was only whenKGB agentReino Häyhänen (a.k.a. Eugene Nicolai Mäki) chose todefect in May 1957 that the FBI was able to link the nickel to the KGB. Häyhänen had been operating in the US for some time, but had been recalled toMoscow for good, and did not want to go. He defected in Paris, on the way back to Russia.
The nickel, it turned out, was an item that Häyhänen had collected from a dead-drop, but which he had accidentally spent before opening it. Häyhänen gave the FBI the information that it needed to crack the cipher - the deciphered message in the nickel turned out to be a message to Häyhänen from the KGB in Moscow, welcoming him to the U.S. and instructing him on getting set up:[2]

Häyhänen (whose code name was "Vic") told the FBI about a number of Soviet operatives in North America, including Vitali G. Pavlov, a former Soviet embassy official inOttawa;Aleksandr Mikhailovich Korotkov; and U.S. Army SergeantRoy Rhodes (code name "Quebec"), who had once worked in the garage of the U.S. embassy in Moscow. The Soviets were able to get to Rhodes because they had "compromising materials" about him.
More importantly, Häyhänen helped the FBI uncover the identity of his two main contacts in New York: Mikhail Nikolaevich Svirin (a former United Nations employee) andWilliam August Fisher, whose code name was "Mark".
Svirin had returned to the Soviet Union in October 1956 and was not available for questioning or arrest,[2] but Fisher was still working in the United States, principally seeking information on the U.S. atomic program and U.S. Navy submarine information.[3][4]
With Häyhänen's help, the FBI identified and arrested Fisher in Brooklyn; the hotel room and photo studio that he lived in contained multiple items of modern espionage equipment: cameras and film for producingmicrodots,cipher pads,cufflinks, a hollowshaving brush,shortwave radios, and numerous "trick" containers.[2]
Fisher, who gave the authorities the name Rudolf Ivanovich Abel, was brought to trial in New York City Federal Court and indicted as a Soviet spy in October 1957 on three counts:[2]
Häyhänen testified against Fisher at the trial.[2][4]
On October 25, 1957, the jury found "Abel" guilty on all three counts. On November 15, 1957, JudgeMortimer W. Byers sentenced Fisher to three sentences to be served concurrently:
On February 10, 1962, after more than four years of his sentence, Fisher was brought to Berlin and exchanged for AmericanCentral Intelligence AgencyLockheed U-2 pilotFrancis Gary Powers, who was a prisoner of the Soviet Union.[2]
