Found this in a bank rolled penny box. Pattern looks to be machine doubling, but I've never seen MD this distinct before. Could go either way, so let's put it up for a vote.
It's definitely MD, i knew that when i posted. This is a textbook example. Mostly interested in seeing the arguments for DDO. Some people just want everything to have value.
It is definitely machine doubling. Distinct? Perhaps you are confusing die deterioration doubling with this example of machine doubling. DDD does tend to get a bit sloppy as the dies get older. ~ Chris
