ksmcents Valued Member United States 306 Posts	Posted 01/10/2015 9:17 pm Going through some RPM's I set aside. I am curious about the circular die scratches on the obverse. How does this occur and when during the minting process? EDS? Report this Post to the Staff

ksmcents Valued Member United States 306 Posts	Posted 01/10/2015 10:14 pm Thanks Coop, is this different from "Concentric Lathe Lines" or the same? These are not as dramatic as what I see on Error.ref. Just curious. Thanks again. Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 01/11/2015 10:29 am Probably not. As lathe lines are more consistent. Note how they are usually the same strength: Note on the lines below the bust how they are not straight and flow over each other. This looks like a cleaning/polishing issue on the die that struck your coin. Report this Post to the Staff
