    1987 LMC with raised area near rim... is it a plating bubble?

    Wanted to know if this is a plating bubble? I tried to pop it and pushed on it with a pen, but nothing happened to it. Here are some pics. Thanks!

      These have been mentioned a lot lately. It's a ridge ring. Caused by a completely worn die.

          Ridge Ring: One of the many manifestations of die deterioration, a ridge ring is a circular area of distortion that goes around the perimeter of a coin near the rim and is the result of cold-metal flow toward the rim from the striking process. These are most commonly seen in the 1980s. Photos courtesy of jay4202472000.

              Nice ridge ring... Amplified a bit by the minor off center strike!!!
