I found this 1924 wheat cent with what appears to be a "D" mintmark punched on the reverse. Anyone have any thoughts on this?
Perhaps a small bit of lamination or maybe damage; I don't know for sure what it is, but I do know what it's not. Are you familiar with what "pareidolia" is? Honest question. Also, from your wording I can only assume this is a 24 philly coin, correct? If so, ask yourself how this could have happened.
Yeah, I'm sure I'm not just seeing things (in reference to pareidolia). It just looks so close to a "D" mintmark in size and shape even under magnification I thought I'd get some other people's opinion on it. You're probably right and it isn't anything.
No harm in getting opinions, and in fact it's probably the wise thing to do. That said, if it would make you feel better, please take the time to very closely compare the D mintmark used at that time to the anomaly displayed by your coin. If quickly compared to the 24-D, it appears to be a bit larger and of a somewhat different shape. If you can do a photo overlay and can properly size both images, this would confirm it. Again, I don't believe any of this necessary, but sometimes going out of our way is a good way to learn. At the very least you'll walk away more familiar with such coins and this could help you sometime down the line. Just food for thought...
I think it's just a hit mark, the old man has a few good ones, between the N E in one, bottom leg of E in cent, But not to bad for a "24". I would like to see the obverse.
Here's a couple better photos. I got the coin back out and looked at it with better magnification and camera. I think it's just a lamination error shaped like a D. I included one of the obverse also. I apologize I should have looked it over better before posting.
I am with books. It is either a lamination or damage. Edit; With the new pictures, a lamination. FWIW, they have not "D's" in Philadelphia.
