Confirmed. 1997P-1DO-001, CONECA DDO-001. Congrats!
It's normally caused by exposure to chemicals after the coin leaves the mint. That's damaged - has nothing to do with the annealing.
The die clash shown earlier in this thread is real and would probably fetch a decent sum of money. Everything else I have seen reported to be...
The thing between the 9 and 6 of the date is the beginning of a die crack, and the other stuff in the date is normal. You have a normal 1960D...
Most likely a coin that has been exposed to environmental damage. Not an error.
The 1942 dime in the OPs post is competely normal. No variety.
The 1971 quarter is normal. Do not use two different years of coins to compare against one another - the designs do change over time. The...
First coin is an overpolished die. No premium value. Second coin is not a CUD. Those are only the result of the edge of a die breaking...
The 1924D that was first discussed in this thread is indeed a CUD, and would have tobe quite scarce at that. Anyone who is trying to build a die...
These are nearly as common as 1943 cents without filled digits. A decent amount of the weakness is due to the strange die wear that shows on a...
And the anomaly is worn die scratches...that's all. The rest is a case of a healthy imagination.
I don't see a doubled die. I see a hit or gouge, depending on whether the area is incuse or in relief. It's not really a matter of 'belief' or...
The part above the D appears to be grime. The part below the D looks like dirt or corrosion. The d itself appears damaged, not doubled.
The mintmark is not doubled, the nose is not doubled, and the thing on the coat is damage.
I see nothing doubled.
My own observation of this coin: EF40 with a light cleaning. Late die state obverse may prove it to be somewhat difficult to sell to a very...
I will have to pull some 1941S rolls out of the bags and go through them just to make sure my averages are right...but I have never had trouble...
The depression tot he west of the mintmark is the beginning of a die chip. The upper serif on that mintmark is very slightly doubled, so it's a...
I have no clue what JC is talking about. There is no doubling at all on the coin, it is completely normal. I have seen a number of times here...
If you want to, you are welcome to send it here and I will take a good look at it. http://www.coppercoins.com/attribution.php
