However, experts caution collectors to be mindful of counterfeits. Some imitations involve altering the number “8” in a 1948 copper penny to resemble a “3,” or applying copper coating to steel pennies to create a similar appearance. A simple way to test authenticity at home is by using a magnet—genuine copper pennies are not magnetic, while steel coins will stick.
If you come across a 1943 penny and suspect it might be copper, it’s worth investigating further. Having it evaluated by a professional coin dealer or grading service can confirm its authenticity and value.
You never know—your next pocketful of change could contain a valuable piece of history. So before you spend that penny, take a closer look. It might just be a hidden treasure.
