Shim Shell Coins allow for truly staggeringvanishes, transformations, and other marvelous effects. The coins are \”shell\” coins that have a shim so they are attracted to a magnet. This is offered as an accessory coin. It does not come with instructions. It can be used with the Raven, RavenX2, and other magnetic tricks. Please Note: Only the blank half is expanded and will fit over a half dollar. The other shells are regular shimmed shell coins and are not expanded, so they will not fit over a coin of similar diameter. Use these gaffed coins with a mini coin of similar value for a shrinking effect, or use alone for a vanish, or change a larger coin like a nickel into a dime, doubling your money. Additionally, the coins pictured are just for reference purposes. If you need to know specifically how our current stock looks, please give us a call.
