1980 10 Cents. Grease Filled Die, Possible Weak Strike Or PMD?

pocket piece ? that would explain a lot..

I think your eyes are fooling you. On the rim pics with only 2 coins, note the reeding looks like a bar on left, the "thin" one on the right, the reeds look like dots. I say it's an optical illusion. If you stare at them for a bit and not look at the reeding stuff, they look the same thickness. The correct weight backs this up. Please measure the thickness with calipers. It will tell you. I think it will be closer than you think. Don't forget to measure the diameter when you check the thickness.

I saw that photo, it just compounds the effect. Calipers for our use are very reasonable. They don't need to be expensive. Can Tire has some. You will be glad to add them to your collecting tool box.

Try this....set your thin coin down on a table beside a normal 1. Then put a straight edge across them both and see if the straight edge rocks.

@loonielewy, took a few photos of thickness for comparison that are more clear that it's not an optical illusion. Put it aside after this.

I'll still have to get calipers but hope this is more clear then having several together in hand. This was tough to get a clearish photo with this new phone.

I had a friend check his 1986 vs a 1980 with calipers and they are the same thickness. I used an 86 as it's what I had on hand. I asked him if I could use the photos to post here to show. They should both be 1.16mm thick.

Edit: that was just a picture to show that it looks thinner then it should, maybe with calipers they would both be the same thickness even though it looks thinner so I'll put this away until I grab a pair.

This is to show these two should be the same thickness, looks can be deceiving so it pointless to Puch this topic any more really untill I can get a legit measurement

First picture is a 1986, second one is a 1980

I have heard of similar things before, I would imagine it would cause the diameter of the coin to be different but it was a while ago that I read an ok it it. I think something to do with squeezing it between leather or something. Ill probably get calipers this weekend and I'll check the diameter as well but seems normal in hand.

It's really hard to take photos like the last one with them side by side, the edge I measured it up aganst was the side of the coin where the rim looks flattened as well, so it would explain why it looks thinner from one side to the next as the rim basically non existent on the reverse on that side where as there is a bit of a rim on the right side of the reverse. The coin is uniform though, it's perfectly round like a normal dime.

Out of curiosity anyone know what a jeweler would charge for an xrf roughly? If after measuring with the calipers if it's thinner with a normal diameter I may take it for one, though like everyone is saying it's most likely PMD. I just like to be sure before tossing it back.

Your most likely correct about PMD, either way it won't hurt to hold onto it untill the weekend to check the thickness. If the coin does happen to be thin, would it still be PMD100%?

@looneylewy, I miss interpreted what you meant by flare out, I see what your talking about on the edge of the rim.

Well even if PMD I'll have some calipers for future posts to avoid all this next time. Appreciate all the responses, I always like to be sure rather then being fairly sure.

I completely agree with you. Most likely the lack of rim and detail on the reverse is all attributed to PMD from the information here. I started looking through the list of foreign coins struck at the in 1980, or at least minted for 1980 and haven't found a match. I only went through half the list so far but I think I was just being hopeful. I'll get calipers and check the thickness out but we can call it an end to this question.
