2021 quarter 2 2

[Hoghead515]

Can anyone tell me what causes the anomallys such as on this quarter? Ive seen them on other coins also. I know its nothing valuable and not worth grading and everything. Im just trying to figure out the cause of it. It dosent affect the device at all but it goes right up to it. I thought MD at first but when I looked under a loupe its raised quite a bit. Also the rest of the quarter is in really good shape. I cant see any signs of a worn die on rest of coin. Its sort of teardropped shaped also. The whole area from the top of his hat to his arm is slightly raised but higher in certain spots than others. By his nose, mouth, and chin is the highest spot. It sort of resembles a die chip. I figured if the die had a tiny chip in it then Washingtons face would be distorted due to metal flowing to fill the chip. Its not distorted at all. Ive seen simular spots like this on other coins and just got curious what causes it. Thank you to all who takes the time to look over this. Im very grateful to everyones responses. Im still in a learning process trying to learn the science of coin striking. And this is an example I can really learn from. Sorry my photos are not the greatest. All I got is junk to take pictures with for now. I tried to capture a couple different angles of it due to the poor lighting I have here.

A little too aggressive ( in that area)  on a die polish would be my guess.

Yes, I see your point.  I've seen that as well on coins.  Not a clue what it is, how it happens or what it's called. Sorry.

Agree with Morgan man. A little too happy with the lapping tool. If you think about it, the devices are incuse on the die, and the the fields are higher. As they polish the die around the devices, which again are inset, if they don’t keep it completely level they start beveling the edge unintentionally.

I need to research those tools they use to polish the dies. Do they still use emry wheels like in the old times?

Good question Hog, maybe @RWB knows how it is done currently.

There is a good video of the San Fran mint guys touching up dies. I’ll try and find it. It’s like a fancy dremel with different heads.  Let me see if I can find it.

I can’t find the video I was thinking about. Here is a couple of pictures of them re-polishing a die to give you an idea.

I remember watching a video the The Royal Mint that showed them engraving and preparing proof dies. They used several different levels of Diamond paste on small pieces of balsa wood, kind of like tongue depressors, to polish the proof dies. Not sure if they repolished them that way or not.

Is that in “Secrets of the U.S. Mint”? I seem to remember a scene polishing a North Carolina state quarter proof die. Or something like that.

It could have been. I can’t seem to find it. But it did have a little scene on die polishing, which I believe they said lapping instead of polishing. But I wouldn’t swear to it.

Secrets of the U.S. Mint was a Discovery Channel property and is currently available on (heaven forfend) YouTube.
