JayCameron New Member United States 41 Posts	Posted 05/31/2015 5:48 pm Hi, I am relatively new to the sub-world of error coins, and I've found some great info. I cannot find out what these circular markings (on obv. or rev.) are, though. Could someone help me out. Attached is an example of a 2012 Washington Denali (USA the Beautiful series) obverse., and also one from a reverse of an Italian coin -- they're common in Italian stainless steel coins, if that helps. Thanks! Report this Post to the Staff

Rollsearcher37 Pillar of the Community United States 1295 Posts	Posted 05/31/2015 6:07 pm to the Community, JayCameron! These marks are caused by coin rolling machines. The part that closes the end of the roll a lot of times scrapes the coin that happens to be on the end at the time. This is considered post-mint damage and brings any value the coin may have had down considerably. Report this Post to the Staff
JayCameron New Member United States 41 Posts	Posted 05/31/2015 6:10 pm Ah, thank you for the quick answer! Glad they're rare in America. I suppose that they're common in stainless steel (harder to damage) makes sense for your explanation -- those who design the machines would worry less about this damage, thinking the material might stop it from happening. Oh irony, haha. Report this Post to the Staff
