This came from an old magician’s estate purchase. Comes with original instructions and the required coins.
The gimmicked coin supplied with this routine was described in the book Sick Sorcery by Olson Pearce.
As stated in the instructions this is for the entertaining magician. If you are looking for deep mystery this effect is not for you.
Basically the effect is that you vanish the coin (which you had a spectator mark) and upon breaking open a cigarette you discover the coin (all rolled up) inside. You give the coin to the spectator who marked the coin and ask them to unroll the coin to check for their mark which they are unable to do. Good for a laugh!
The detailed instructions give all the details for performing the routine.
