In the mid-1950s Francis LeRoy Henning of Erial, New Jersey minted what is now known as the “Henning” Nickel. He made counterfeit nickels dated 1939, 1944, 1946, 1947 and 1953. The 1944 nickels were quickly spotted since Henning neglected to add the large Mint Mark.    The 1944 Henning Nickel is easy to spot because of the missing Mint Mark. But the other dates 1939, 1946, 1947 and 1953 are more difficult.   These are identified by a mistake on the die that Henning made that has a hole/looped “R” on “PLURIBUS” on the reverse side which gives it a very distinct look but not all reverse die has this mistake. The Counterfeit’s Weight is ~5.4 grams while the Jefferson Nickel is ~5.0 grams.
