I decided to go get a few rolls of nickels to change things up. I did find a 1945 P War Nickel in the same roll! This 2018 P Jefferson nickel has close to the same doubling as the 2019 P but not quite as strong. Tell me what you think.
It could be a new one. (Or a listed one that doesn't have markers yet?) You might check with Brian and see what he thinks. Images of the DDR and images of the marker areas that he has listed. Also add any markers you might have on your coin. Maybe a match to a different die state, or a new die number?
