This is the finest shim quarter made (attracted to a magnet). Undetectable. Can be attracted to a magnet for many effects. Use this with the various Raven effects as well as anywhere you need to steal a coin using a magnet such as a Matrix routine. Can also be used in various cup transposition effects.
Works great with our new Quarter-Go Plus Box.
This coin has a METAL shim inside, not a magnet.
