Bob Swadling is commonly credited with the invention of the Flipper Coin. However, Dan LeFay reports the following information received during an interview he did with Eddy Taytelbaum. In the mid-1950s Eddy Taytelbaum came up with the idea of using a Folding Coin to represent two coins. Shortly after this he came up with a Coins Through Table routine, using a Folding Coin (an idea David Roth chanced to reinvent independently some years later). In 1959, this line of thinking led to his inventing the Flipper Coin and, after performing a bit with it, he made and sold a few to European magicians. Flip Postma showed the gimmick to some magicians, including Bob Swadling, at a British convention in the mid-1960s, where Swadling asked for permission to make one for himself. Two years later he told Taytelbaum the gimmick had “made him a small fortune.”
