Random Letters On Obverse/Reverse 1952-D Wheat

I thought it might be RPM, but I quickly checked and did not find a match. Perhaps a more careful search?

I love this site but it seems that there's a quickness to debunk anything posted here. Is this the case? This coin has a clear letter in each side and it's called damage. I've taken coins called damaged here to a specialist in person and told it's a double die. Idk what to believe.

1. We like discoveries and finds. We wish yours was something great but its not. How and where in the minting process do you imagine this kind of error occuring? The minting process is known well enough to rule this out of possibility as an error .
2. Seems kind of strange that the coin you were told was damaged here was later verified as an expert as a doubled die. What kind of damage did they say it was here? What kind of error were you thinking it was? Who was your specialist?
We would of told you it was not actual die doubling but one of the other types if you asked about that. If not, the fact its a doubled die or not doesn't matter because it would still be damaged.
Can we please see the coins in question or a link? If you asked here it'll be easy to find your old threads where you asked about these other coins..

I wasn't referring to this coin as being double die, just speaking in general. I can't explain it and so I present it here as well as to share its rarity.

One of the first questions I ask myself on a coin this this: What in the minting process could have created this anomaly?
Having knowledge of how die are created, knowing what thing can happen during the striking process, and what can happen after the coin is struck helps a lot.
If the area in question that we might think is a something is smaller/larger than any device on the coin, then it is just our eye tricking us into seeing something that is not there.
A lot of coins we have posted here we all damaged after the strike. We try to figure out how that happened. On your coin, it may have spent a time in a parking lot and a stone made the indent on that area. But note I mentioned indent? If it were something on the die the area would be raised, (the die is the negative) and be the same size as other devices. If it is not, then it did not occur during the mint process. Thus we determine it as PSD (Post Strike Damage) or PMD (Post Mint Damage).
Many times we will get questions about something that looks like a letter and it is level with the fields. This could not be a strike issue as it is not raised. (Incuse on the die, leave a raised area on a coin)
So we are asked the same questions over and over, but try to explain them as best as we can. (we can't follow around each coin during it's life, so we have to give out opinion)

Thing happen to coins. Some are experimented with to make an error. What happens when they can't create the error they want to make? They spend the coin. Someone else finds it and runs with it.
So we are not making quick judgment, because we have seen a lot of the same things over and over. When someone asks a question that I don't know for sure, I may not answer it then. Sometimes I give it though and later come up with the correct answer. Sometimes we are wrong and other experts are called in to help. So if I don't know, I don't answer.

I may need to look up more information to ID a variety.

But I take the time to give the best answer I can give.

I do not understand what you are asking That is a picture of a typical off-center strike, there is no "missing layer".

I thick the hot grease makes a lasting impression sometimes...........
