Hay there all i'm new to the game and while going through some coins I found this On the back near the 'I' in UNITED is where I was looking.
Yep, it's a die crack. It also continues from the bottom right tip of the memorial building to the rim. It's one of the most common types of errors though.
Ok cool Numismat I'm just glad I Found something. I still have a ton of coins to go through.......it never ends but I love it.
