The O took a hit, the metal moved on one edge to make it look like an upside down D. I don't believe any dealer told you this is a mint error. This is a damaged cent worth 1 cent. This doesn't happen at the mint.
It would be unethical to say or imply that this coin might be an error when selling on ebay. Listing it as anything other than a damaged coin would be lying. Please don’t suggest that the OP should try to cheat others. That’s not right.
Please don’t post completely inaccurate information. Many new collectors use these posts to learn about the minting and die making process. Coins are not heated when struck, nor is any frictional heat that might be generated, hot enough to soften metal. Members on this site have posted a number of useful links that explain the minting process. Check them out, and feel free to ask questions. Anything from basic process flow to advanced metallurgy and chemistry, there is member who can give you an accurate answer.
@Jasongj ...You are welcome to frequent coin forums elsewhere, you won’t get any help acting like this...at least, not from me...Spark
Why would you even suggest something so ridiculous as this. It's damaged and you are telling the op to be dishonest. At least we know where you stand.
Since our original post, we've shown this coin to 3 different dealers. These people have had this coin in their hands, looked at it under magnification, and agree that there is no damage from circulation except for a ding halfway up the straight bar which is easily visible even from our poor quality picture. The explanation that was given to us is that the coins struck before this one were showing a die crack on the zero. This coin was struck after the die crack turned into a die break, with the chip remaining in the die, but slid to the lower right of the zero. Coins struck after the chip fell out would show a cud covering from the crack to the lower right of the zero.This is one of the very few out of the 610 million Lincoln cents struck in Philadelphia for this year. We're now looking for a 1980 Philadelphia Lincoln cent with a cud in this location which will verify this explanation. I'm attaching a sketch to illustrate this explanation.
I don't know who the dealers were, but that explanation just doesn't hold water. Any chip or break in the die would leave a raised area where the piece of die broke away from. It just could not happen as you explain. I guess the best thing for you to do would be to send it to one of the major third party graders for attribution.
Sharon, none meant anything personal about the coin. I agree few of us would agree with the dealers you consulted. Being a PCGS dealer just means they can send them in for grading and have proper papers. The PCGS fee would be $95 total for 1 mint error coin and return shipping. I think it is damage from an old coin counter. Jim
Here is a better quality closeup where you can see that the metal on the straight part of the zero is raised up the same as the rest of the date. There is no damage in the field or on the rim.
if you look closely at your image, you can see the surface anomaly of where the metal was before it was pushed off. But, it's best to just send it to PCGS and prove to THEM https://www.pcgs.com/onlinesubmission
Oh god. This again. In the time and money you spent running that damages cent all over the place, you could have sent it in to be verified. why don’t you come back when you’ve done that and have a real answer.
If you look at the damaged 0 you can see a hit on the straight part and as clawcoins said, you can see the faintness of where the 0 was before it was moved.
That is an excellent picture, thank you. It does show even better what we have been telling you all along, it is damage. You are not going to convince the folks here that it is an error, if you are that convinced the next step is to send it in to be attributed.
