Found a new 2016 Shawnee Quarter with doubling around the edge. Could even be tripling on the 'E''s in Shawnee looking at the lower serifs. Don't have another coin to compare in the field for anything.
without pictures no one knows, but the best thing to do is start your own thread so more people may see it and you get more responses.
I did not. I had sent in a 2015 Quarter with the same type of 'doubling', which turned out to be DDD. I'm keeping it back just to have as an example, but I don't see any reason to send it to him.
