You have a good eye, young man! Congrats on your score in the grading contest, too.

What were the die markers that convinced you that yours was indeed a proof?

It must be my phone, but I only see one picture of the Peace dollar reverse.

Two nice finds

I have done research on improperly annealed coins, and what you described - molecules migrating from the copper core, through the clad layer, to the surface, and doing it while the coin is in circulation, cannot and does not happen.

Have you been drinking?

Yes. The OP's coin appears to have simple environmental damage, so i don't think it applies, but here is a section of an article by error coin dealer Jon Sullivan: One other type of missing clad layer is called a “dual missing clad layer,” which is a coin missing both the obverse and reverse clad layers, with only the copper core remaining. Such a coin will be copper on both sides and will weigh approximately 30% less than a normal coin of its type. The dual missing clad layers are incredibly rare, with less than 10 known for Roosevelt Dimes, five to 10 for Washington Quarters, and only one for Kennedy Half Dollars, and none are known for the dollar coin series.

This is the first time I have heard this theory. Can you explain how it is possible for copper to migrate from the middle of the coin to the outside of the clad layer?

Although I don't think this is true hub doubling, I hope I am wrong, and the OP has made a new discovery. If you decide to pursue this, I suggest posting on the coneca forum as suggested above, and please keep us informed.

If you are talking about the appearance, it looks like someone has attempted to clean it, or the surfaces have been messed with some other way. If you're referring to something else, please specify.

I am not connected with NGC in any way, but I can offer an opinion. Recent "sold" listings on Ebay show these 7k state series eagles in MS 70 selling at prices from $50 to $80. If you are only being offered $25 - 40, you might want to consider listing them on Ebay.

In the grand scheme of things, it doesn't mean a thing, but I took a shot at guessing what the OP was talking about. I did not want to post it until the OP had a chance to answer. I typed a post and saved it, though. Looks like I guessed correctly. Here is a screenshot:

Unlike most other collectors, that fingerprint on the 1911 does not bother me. The little round spot in front of Lincoln's upper lip does cause some concern, though. Still, I intend to keep an eye on it when it comes up for auction.

So, do you think this was one of those "midnight shift" jobs?

Nice looking quarters. I bet the hunt for these is a lot of fun.

Part of the price disparity is probably because the top (NGC) coin is silver, and the bottom (NGCX) is clad.

You can't post something like that without showing pictures.

Until the last quarter of 1942, nickels were made of the regular copper-nickel alloy. When the composition was changed to copper/silver/manganese, the large P,D,or S mintmark was added over the dome of Monticello to denote the different composition. The copper/nickel coins from Philadelphia had no mint mark, and the Denver issue had a small "D" to the right of the building on the reverse. Your nickel is a Philadelphia Cu/Ni coin. The dark gray patina is not unusual for coins of that era.

A PF70 ultra cameo quarter is worth a few hundred to the right buyer, so if you are seeing prices higher than that, it is likely clickbait. i can relate, though. I saw an article this morning that had a title claiming that certain bicentennial quarters were worth $80 million.

I did not set any goals for this l past year, but I was able to add 41 tokens to the collection, along with a couple of interesting US error coins and some world coins that caught my eye. All-in-all, it was a good year for all my collections.

The "O" is next to the "P" on a keyboard, so my guess is that the title has a typo, and the OP meant to type "RPM." Welcome to the forum, Gary. You might wonder why you were asked to supply photos of the complete coin, front and rear (obverse and reverse.) The reason is that later die states of the D over horizontal D variety can possibly be confirmed by various die scratches and breaks, assuming the coin is not too worn to see them. You might want to take a look at the Variety Vista page for this coin, since you have it in hand, and compare it to the pictures and descriptions there. Here is the link: click here

Welcome to the forum. Your coin looks like it has spent some time in the bowels of a commercial clothes dryer or some other machine that has worn down the edge and one side. It is not an error coin but is merely damaged.

98E, huh? Does that mean between Hattiesburg and Lucedale?

Welcome to the forum. Have you weighed the coins? They need to be weighed on an accurate scale that reads in grams to two decimal places (hundredths of a gram). There were two different cent compositions that year, as I am sure you know. The copper-coated zinc version should weigh around 2.5 grams, and the brass version should weigh around 3.11 grams. Be sure to orient your pictures correctly and crop out all of the background. That makes it easier for all of us old men on here to see what you have and offer help.
