I'm am just a retired novice collectorand I enjoy eyeballing all coins. While going through a pile of wheaties last night, I came across a mark that has me baffled. The coin is a 1952-D Lincoln. The marking is on the 'D' At the top of the D there is a horizonal line as thick as the back of the D, but then there appears to be a lava flow look under the horizontal line. Try thig of it as a 'Harley Davidson Wing off the back of the D mintmark. As soon as I figure out how I can have a scanned image of the marking published for viewing.
