United States Eisenhower Dollar Cold War SPY COIN

United States Eisenhower Dollar Cold War hollow SPY COIN with secret compartment 

Covert spy coins are hollow coins used by agents to carry data either in the form of microfilm or, more recently, electronic data cards, which are concealed in a hollow compartment. 
This original Eisenhower Dollar coin is expertly precision hand-machined from two actual coins to create a secret interior compartment. Once closed, it is  absolutely indistinguishable from a regular coin to the naked eye. It can be handled normally without any chance of an accidental opening. The coin is supplied with an opening device, without which it's next to impossible to open up the coin.
Diameter 38mm.  Dates may vary- coin only NO data card included.
