I was looking at a Washington State 2007 coin. On the back of the coin a Capital "E" is stamped into the middle of the coin on the mountain. The size of the E is slightly smaller than the mountain.
Someone used a letter punch to mark the coin. It was not done at the Mint and is therefore a damaged coin. Thanks, Bill
Thank you for you reply. I felt that might of been the case, but I wanted to be sure. Have a good day.
