Nathan Kaplan, also known as Kid Dropper, was one of a number of powerful gangsters who were active in the pre-Prohibition era of New York City history. He was probably the most noteworthy racketeer at the outset of the 1920s. He acquired his nickname by running a scam that conned people into buying a wallet that he had found in a puddle of water. He asked only that he be paid a reasonable amount because it had money inside and he had decided against searching for its true owner. The only hitch is that the wallet was filled with counterfeit money so the buyer had purchased something without any value. Another story circulated about Kid Dropper is that when he hit people with a blackjack they dropped.
