I found this going through my pennies. It's not an error coin, (unless I'm missing something), so maybe this is the wrong forum to post, but I wondered if anybody had an idea what caused it?

The "holes" are deep (there are bumps on the obverse) and kind of pyramid shaped. Very even spacing.

Probably damaged in a vise with those indentations on the grippers. PSD spendable.

I've seen similar marks on a bolt on a toilet at work, I guess from some sort of wrench. Very possible a maintenance guy put a penny between the wrench and the bolt so it would get messed up instead of whatever was being tightened.

I agree with the previous posts, but out of curiosity, could we see the obverse?

See how the dents are deeper towards the center? Just like what you would see if someone struck it with a hammer that has a slightly rounded face such as the one shown. The other side most likely had flat spots on the same area from the pressure.

with cwb. The pattern also reminds me of what I've seen on some meat tenderizer mallets. Thanks, Doug.

Here's a pic of the obverse. It's hard to see with all the gunk (tried to clean it off, but it's pretty stuck), but there are raised bumps. Wouldn't it stink if this were a 1943 copper?

The hammer theory sounds as good as any. Thanks!
