How Much Does a British Penny Weigh?
The Royal Mint states that the British penny weighs 3.56 grams. The penny was first issued on Feb. 15, 1971. It was one of three new coins that were introduced after a new decimal currency system was implemented by the United Kingdom.
The other coins that were introduced because of the new decimal currency system were the 1/2 penny and two penny coins. All of the coins featured the word “new” incorporated into their reverse designs to help avoid confusion between the old and new coins. The word was finally removed in 1982. After 1992, one penny coins were struck in copper-plated steel instead of bronze because of the increasing price of metal.
