Thanks for the help! I have a question about the doubling I am hoping someone can answer: Is it possible for a coin to have some
Machine Doubling and also
DDO features? The only reason I ask is because I see flat field doubling on some devices like you guys have said, but I also see some devices with extra rounded features that I thought would make it a
DDO. Also, does the fact that it is from the San Francisco mint mean anything? I ask this because I don't know if they have a different way of minting coins. Do they press the coins more than once and is this result?
