A coin trick precision made from a special Houdini Coin and a Mexican 20 centavo piece. You put both coins into the spectators hand, in full view. The gold coin disappears and can turn into a "MAGICIANS'S COIN". Routine shows you how to win a "Scotch & Soda" each time you do the trick. Can be freely examined at end of the trick.

It is entirely mechanical and easy to do.
