The Houdini Coin was specially created by the DP Group to commemorate the 80th anniversary of Harry Houdini's passing. The coin measures 30.5mm in diameter and 2.4mm in thickness, making it nearly the same size as a half dollar. Both sides feature a raised relief portrait of "Harry Houdini." Since the design is the same on both sides, you can perform various coin magic routines without worrying about which side is facing up. (Its sparkling beauty makes it perfect for stage magic as well!)
