Any pennies like this were purely accidental and are extremely rare today, which is why they are so valuable. Just check any you find with a magnet to make sure they’re the real deal.
A copper penny dated to 1943 is likely to be worth approximately $85,000 if it’s in good condition.
A mint-condition, untouched penny could be worth a great deal more to the right buyer.
Even a solid penny from that year that is damaged could be worth quite a lot of money.
That’s why you should take a good look through any coins you have at home to see whether you might have one that fits the bill!
