it's probably a magician'S coin.
Give that man a seegar!
US victory nickel 1911, the insert is a 1928 penny, plated and stamped as a nickel.
Don't light it.
Just a V or liberty nickel, not victory. The 1928 cent hasn't been plated, just attached to the reverse of the nickel after it was sanded down.
I believe it is a spy coin of some sort.
Not a spy coin. There would be no point in putting the cent in there, it would only take up space.
I have a Kennedy half that opens up but there's only room inside for microfilm....spy coin?
Poor mans opium dollar?
Nope, see spy coin explanation.
Nice find, and pretty old magic trick.
