Need a full picture of the coin. The pictures are nice, but do not show the whole picture, to make a good determination of the cause.
abuckmaster147, I posted this because the only part that appears flat and shelf like is in the M the rest of it is just lines when you look a little closer which might put it in a category of Trails and Wavy steps when looking at Lincoln Source. Although I did post as a possible DDR! Thank you for the help it's much appreciated !
