Mercury dime mintmark oddity

[jesbroken]

Hello, all. first post so if I screw it up-apologies. I have a 1942 D Merc that appears to have a mintmark overstrike of another mintmark? just an opinion. Please take a look and tell me what you think. Thanks in advance. Jim

Hi Jim and your post came through fine.

Looking at your pictures, it appears to be machine damage doubling (MDD), common on mercury dimes, in fact common on most all modern dimes. The flat field affect, the scrape marks on that area and the absence of a lower continuation of the mark all point to this not being a RPM.

What I'm seeing is a low, raised feature beneath the D that resembles the upper half of an S. However, its curvature seems a little off for a mintmark trace and it also seems rather thick, relative to its height. My guess is that it's some die damage that coincidentally resembles a letter.

The upper serif of the D-mintmark, and perhaps the vertical bar, appears to be flattened as a result of post-strike damage.

I don't see anything where the arrow is pointing. The upper serif of the mintmark has circulation damage. There may be a little MDD to the North (shiney area). The bar in the center of the mintmark could be the bottom of a repunched D. The coin needs a little soap and water to get the dirt off and then a fresh examination.
