The Story Behind the Coins

During the height of the Cold War, spies from both East and West relied on hollow coins to transport secret messages, microfilm, and even suicide poisons without detection. These seemingly ordinary pieces of currency could pass through any checkpoint unnoticed.

May 1, 1960: U-2 pilot Gary Francis Powers was shot down over the Soviet Union. Among his possessions was a hollow silver dollar containing a poisoned needle—his final contingency plan. Powers was captured and held for 21 months before being exchanged for Soviet spy KGB Colonel Vilyam Fisher (Rudolf Abel) at the Glienicke Bridge in Berlin.

Colonel Fisher was no stranger to hollow coins himself. His 1957 capture by the FBI was directly linked to a hollow nickel used to transport microfilm containing classified intelligence. A Brooklyn newsboy had accidentally discovered the coin when it split open after being dropped, leading to one of the most famous spy cases in history.

Today, we produce exact replicas of these historic espionage tools. While the technology hasn't changed, the data storage has evolved—our coins are now machined to conceal MicroSD cards with capacities exceeding one terabyte.

How Our Hollow Coins Work - Precision engineering meets historical espionage

  • Precision Machined

    Each coin is carefully machined from authentic U.S. or foreign currency using specialized equipment to create a hollow interior chamber.

  • Friction-Fit Assembly

    The two halves fit together with such precision that they remain securely closed during normal handling and can even circulate without detection.

  • Disassembly Ring

    Each coin includes a special disassembly ring. Place the coin in the ring and tap on a hard surface. The halves separate instantly for access.

  • Concealment

    Hide MicroSD cards (up to 1TB+), folded notes, codes, or other small items. Completely invisible to the naked eye when assembled.
