Not a low pressure strike because the reeds look strong and the rims are well developed. Mike Diamond wrote an article for Coin World about the Mankiller quarter with the obverse Cud and reverse die crack: Of note, he had this to say: Quote:For his examination of the first error quarter dollar Clark located, Diamond said, "Lucky collector. These coins have been selling on ebay for more than $300. These images represent the earliest die stage I've seen. The early stages seem to have been Struck Through Grease or maybe they were weakly struck. "It's hard to say which without a shot of the edge. The well-struck area within the Retained Cud suggests it's grease, since Retained Cuds are often less well struck than the surrounding area." Here are two recent examples of the error that sold on ebay: Notice that these two error coins show many of the same features as the OP's coin. Specifically, these two examples show the same device effacement at the rim as well as some of the same reverse effacement of devices. Notice how the WIL is strong but the MA (of Wilma) is very weak on all three coins. Likewise, the KI of Killer is weak, while the first L is strong and the second L and E are weak. There are many more similar weak spots as well. Did all these coins come for the same set of dies? Is it possible this is an early die state of the error coin before the Cud formed? Edited by HGK3

@ HGK3: I Know this study from Mike. The question it is and Retained Cud will affect the middle of the coin? and only one side middle?, which it is the case here. Do we have to ask Mike to look at this coin? Edited by silviosi

Sil, Are you saying that it's PMD that affects the middle of one side of all three coins? Is the sample with the obverse Cud and the same device effacement on both side PMD for the flattening but a genuine Cud? What about the sample with both the die crack on the reverse and the obverse Cud? Did someone find that obvious error coin and then intentionally flatten the devices on both sides? |

I have no idea if they implanted my next quote because in 2021 I finish the contracts (personal states). I think you know the study of 2020. In 2020 we see that will happened if the Dies will not be change metallic or hardiness. Quote:

When comparing thickness like you posted here, angle and alignment is very important. If the lens and coins are off at all either horizontal or vertical or left or right front to back one coin with look thicker. Plane of view, learned that in mechanical drawing class. Try for a straight and level picture.

Sil, I mean this as respectfully as possible: I have no idea what you're referring to. Your original response to the OP's coin was: Quote:
This is IMHO an hand made simulation of an error after Mint Strike. My question is simple - are all three coins with substantially similar markings (the OP's coin and the two ebay coins I linked to) PMD? |

@ HGK3
Yes. From same location. PM me to can give the material testing and follow the origins of the coins.
PS. I have one and tests are as the metal tests.

As HGK3 showed us those ebay listings of the Retained Cud and bilevel die crack the characteristics are similar on the coin not to the extreme ofc and that's due to grease. OPs coin is a grease strike plan and simple. As it relating to the retianed Cud and die break reverse two separate dies. It does seem the mint had an issue with grease bc we've seen a lot of grease strike thrus like this on the man killers. Months before. Here is a retainer Cud with a bi facial grease strike similar to OPs quarter ofc no Retained Cud but this is just to give an example to show that ops coin is legit a mint error.   And below is just the Retained Cud no grease strike  NEXT Edited by gorham_collector

As others have said, the OP's quarter was struck through "grease" on both faces. You would need a common die marker to connect this coin to the Mankiller quarter with retained obverse Cud and (later) the reverse bi-level die crack. Error coin writer and researcher.

Got back yesterday from vacation and I was able to weigh the quarters on my brother-in-laws digital food scale while we were there. It can weigh in both ounces or grams, both quarters are exactly the same weight at 5.6 grams. I looked this up and that is very close to what they are suppose to be. Thanks for the input from a week or so ago, any other ideas on why the edges are so weak?

So I take it from the comments it is likely a grease strike through, so these are not that rare then?
