In 1943, the U.S. Mint made pennies from steel due to wartime copper shortages.
These unique pennies are coated with zinc to prevent rust and have a distinctive silver color.
Most steel pennies are worth 10 to 50 cents, but in pristine condition, they can fetch more.
Error coins, like the 1943 copper penny, are highly valuable and sought after by collectors.
Condition is key; pennies graded 'Mint State' can be worth significantly more.
Look for the mint mark under the date; 'S', 'D', and no mark represent different mints.
A 1943 'D' mint mark steel penny in good condition can be worth more than those without.
Counterfeits exist; authenticating with a professional can ensure the penny's true value.
Special editions, like the double die obverse, can be worth thousands of dollars.
Keep an eye out in your pocket change; you might find a piece of history worth more than face value.
