JFK - 1982 P - No FG / Partial G Etc

If I understand correctly, the no FG is from an overpolished die. If that is the case, MAYBE your G/faint G are stages in between. Can you see the telltale scratches in that area? Just wondering if you do, if they match each other. You might be able to see the sequence in them. That would be really cool!

There are some more seasoned pros on here that can answer your questions better than I can. I'm not sure if they are technically considered errors. I don't personally consider them errors, but more like "different or interesting" at best. But, yes, I do keep them, especially the more dramatic ones.

I'm sure there may be many reasons that a die can get polished, but one simple reason is in the case of a die clash. If the two dies come together and there is no coin between them, sometimes they can leave impressions on each other. Sometimes these impressions will show up on the coins minted after the clash. Sometimes, after a clash, they will take the dies and "polish" away the marks that have been left behind. When they do this, they leave behind the minor scratches that you see. (Look at the missing Lincoln pic I posted and you see heavy polishing and scratches.)

Like I said, more seasoned pros could explain this better and give more examples. I'm still new to all of this, but I try to answer questions because I know it can be frustrating to wait for a response, and also when I'm wrong - you'll hear about it and definitely get an answer!

Plus, I think it is only fair that newbies answer newbie questions that the pros have already answered a gazillion times. It's time for us to pay our dues and let them answer the more in depth questions that you and I will be asking later on as our collecting maturity grows.
