What is a coin - a spy?
Coin is easy to rotate in a box.
The blow on the box, the coin flies out of her

Magic coin trick. The smaller coin disappears when the hollow coin is placed on top

Thank you for your comment ...

Maybe someone will tell the Swedish forum, I want to ask them ...??

I think I have a coin, a coin like this ...

Monentu-cache worked for the KGB in the 1950s: a hollow coin could come in handy for storing spy microfilm and microdots. Opened with "secret" with the needle, push in the small hole on the front side of the coin. The second type of coins came later: it was the coin-spyware, transmitting a signal on the location scout.
