"Spy coins"—historically known as "opium dollars" or "smuggler coins" are crafted from 19th-century silver. History and Purpose The 19th Century Origins: In the late 1800s, real United States Trade Dollars were frequently hollowed out by skilled machinists. They added a microscopic, hidden floating hinge and release mechanism to create a secret locket. These were colloquially rumored to smuggle small valuables, secret messages, or contraband like opium, though they were often just novelties or personal lockets. Cold War Espionage: The concept was heavily adopted by intelligence agencies like the CIA and KGB during the Cold War. Spies used modified, hollowed-out coins (such as nickels or silver dollars) to seamlessly pass through security checkpoints while concealing microfilm, secret communication codes, or emergency suicide pills. Modern Use: Today, precision-machined "covert coins" are still manufactured and sold as novelty items. They are heavily utilized to physically secure and hide digital data, as their internal compartments are perfectly sized to conceal micro SD cards.
