As you know, coins in Europe and the US have an unfortunate recent trend: the backs of the coins are all different! When you borrow a coin to perform Coin in Bottle, you never know what kind of back design you will receive.Problem solved! Now Tango Magic makes double-sided folding coins for just this purpose. This way, at a quick glance, the coin inside the bottle will always match the one you borrowed!This coin is available in quarter, dollar, and 50-cent Euro coins. Better still, each package includes an instructional DVD explaining a spectacular handling for Coin in Bottle.
