Noticed ridge ring on the both sides of your 1985 LMC, also, indicating die deterioration. We all keep what we like. I have a couple of Zincolns I placed in 2x2s that are riddled with plating blisters. I keep them as good examples of the issue.
Here at Mile high, I have never had a plating blister go south on me. It all depends on what climate you have them stored in. When I was in TN, It seemed that even new bank rolls had problems.
It is an interesting anomaly with face value only. I would keep it for show-n-tell and for pleasure also. Thanks for sharing.
