A 1943 copper penny is worth a small fortune.
Pennies were made of steel that year because of the needs of the War effort. A handful of copper blanks were accidentally minted along with the zillions of steel blanks.
Bottom line....the few known copper 1943 cents are mucho valuable.
Of course, some criminal types over the years have taken ordinary 1948 copper cents and scraped off the left side of the number “8”, making a forged 1943 copper cent. Gotta watch out for those.....
I had one one time- but it was magnetic.
