*** Edited by Staff to Add Year / Mintmark / Denomination to Title. It's essential to have it in the title. ***

I know you've seen them. Not exactly rare, but far from common. Sometimes one, but usually a set of two or three teeth marks, usually expressed as gouges, but occasionally as dents. Only one or two per coin, very random in orientation, usually on the obverse. Dimes to dollars, they all get it except for cents, I have only seen it on a couple of them.
I was mentally putting that profile together while looking over this mid-twentieth century collection, they kinda stand out in a survey like that. So when I finally looked at the mint uncirculated sets, I was not surprised to find that the call was coming from inside the house, they are there too.
Has anyone gone to the mint to find out what machine is doing this? Would marks like this knock a coin down a couple grades? Why is there not a line at error-ref just for these guys? They are way cooler than 'feeder/ejector scrapes'

To CCF! These are called Reed Marks. They're not errors, just PMD.

Those are Reed Marks, PMD, from another coin.

to the CCF and This question is probably in the top 5 questions we get here. They look good until you learn what they are. And dimes to dollars do have more of them because from the second after they are minted, they are running into each other.

Ah, cool! Or not cool, I guess. I did a few forum searches and didn't come up with anything, I shoulda put some more thought into the spacing of the teeth

...and you wouldn't expect things of equal hardness to inflict that kind of damage to each other, but of course the reeded edge would be more work-hardened than the face. Quite a bit harder, it seems.

People did bite coins a hundred or more years ago to test for real gold & silver content.
Try biting a Cupro-Nickel coin and your teeth will likely pay the price.
