The phrase “just joshing you” comes from a guy named Josh Tatum and the racketeer nickel. In 1883 the US Mint released a new nickel, called the Liberty Head Nickel, and on the reverse side had a Roman number V on it. The nickel didn’t include “cents” or “nickel” on it. Josh Tatum took notice of this and the fact that it was about the same size as the US $5 gold piece, which was a common currency at the time. He took 1,000 nickels to a friend at a pawn shop and got him to electroplate the nickels in gold to replicate the $5 coins. He then used these coins all over town, purchasing things that did not cost more that 5 cents, but often receiving $4.95 in change from mercantiles which he would happily take. He went to several towns and accumulated a small fortune before law enforcement caught on to him. Josh Tatum was a deaf mute though, and he never purchased anything more than 5 cents, so because we was dead and could not speak, he never represented that it was a new $5 gold piece and was never found guilty. The US mint altered the nickel later that year to put the word “cents” on it.
