1922-D Lincoln, No D, Strong Reverse, Die Pair 2 Front
A damaged die or two at the Denver Mint led to coins with no mintmark. While most unmarked coins come from Philadelphia, the only mint to make pennies in 1922 was Denver. About 15,000 to 20,000 coins were made this way! This one weighed 3.11 grams and was made of copper, tin, and zinc.

You will notice that the image on the other side is sharper compared to the face side. What gives? Well, this actually makes sense since the back was struck using a fresh die. This is why it is a lot clearer. In March 2018, a red coin in excellent condition went for $63,000 in Baltimore!
