This cup serves two purposes. First, it looks the same as the Shamrock Cup and Lots-A-Coins Cup, but it isn't gimmicked. You can switch it for one of the gimmicked cups and have it examined. Or, for a funny finish, ask the spectator to put the coins back into the cup. To their surprise, they won't even fit into the cup!! Your Leprechaun Coin Cup set won't be complete without the Sucker Cup!
