“The 1943-D bronze cent is the most valuable cent in the world, and it took four years of aggressive negotiations with the coin’s owner until he agreed to sell it,” said Laura Sperber, President of Legend Numismatics. Even if your 1943 penny is made of steel, it could be worth more than its face value.
Can a bronze copper penny still be made?
Sadly, there are many ways to physically and chemically change the look of steel so that it has that brown bronze copper color. Bottom line is, if it sticks to a magnet then you don’t have the rare version. Sorry. And don’t celebrate just yet if it passes the magnet test.
