I want you to think about this story next time you see a penny laying on the ground and don't pick it up. Turns out that when copper was needed to win World War II to make bullets bullets and wire, one of the most valuable coins in US history was created in the US Mint in 1943. The Lincoln penny. To preserve the metal, 1943 Lincoln pennies were made of zinc-coated steel, but a tiny fraction of the pennies put into circulation wound up using all copper.
The 1943 Lincoln Penny is made of copper and is considered the "most famous" coin manufactured by mistake. Only 20 were ever made and the US government has denied its existence for years. One coin was found in March 1947 by Don Lutes Jr. in his school cafeteria. Now that penny is set to go up for auction.
Lutes just passed away in September and now the coin he found will go up for auction and nobody is really sure how much it will go for. Estimates have the penny selling for as much as much as $1.7 million dollars.
