1943 Penny
In recent years a “1943 S” (San Francisco Mint) copper coin has gone for about $60,000 dollars at auction. I remember the prices from the P (Philadelphia) mint ranging from around $10,000 many years ago to $73,000 in recent times. There are many counterfeits of this coin.
The easiest way to determine if a 1943 one cent is made of steel, and not copper, is to use a magnet. If it sticks to the magnet, it is not copper and is worth about 50 cents. If it does not stick, the coin might be of copper and should be authenticated by an expert.
