Tric-Tac
Bob Chesbro

A marked coin appears inside a clear box of Tic-Tac mints!

Borrow a coin and have it marked. Hold the coin in your hand while you bring out a box of Tic-Tac mints.

Open your hand and the coin has vanished! But...what's this? There, inside the box of mints, is the marked coin! Show the mints all around, with the marked coin rattling around inside. Magically, remove the coin from the container and place both on the table. Both the coin and Tic-Tac box can be handed for examination!

No switches. No wax. No threads!
