Got this NGC Slabbed MS 66. A couple questions.
should I get it regraded? It’s an older case and I wonder if it would grade 67.
I can’t tell if it’s the case, lighting or both, but it almost looks like a slight RPM.
Any thoughts?
Thank you in advance. Sorry if pics aren’t great.
Found this 1939 Mercury dime while going through a silver lot and noticed a really unusual raised area covering most of Liberty’s face/forehead.
At first I assumed environmental damage or corrosion, but after taking macro and side-angle photos, the metal flow and surface texture look more integrated into the strike than I expected. The area appears raised rather than sunken, and the rim/reeding still look normal.
A few people suggested:
struck-through retained debris
heavy grease strike / filled die
retained die break or late-stage die deterioration
I haven’t been able to find another documented 1939 Mercury dime with this exact appearance.
Not claiming anything definitive — just trying to determine whether this is:
a legitimate mint error
or
post-mint damage that happens to mimic one
Would appreciate opinions from error specialists or Mercury dime collectors.
Wondering if I should get these graded or keep in cellophane as a set. Any marks I have seen are on cellophane. They stay in place when I move a coin.
