Hi, I have done coin roll hunting and thought it would be interesting for a change to not look for errors in circulated coins and change, but rather, to try and find error coins crispy fresh from the U.S. Mint in BU condition. I would therefore have error coins, if any, that their entire history would be known from receiving them and I would also have an opportunity to find mint errors before circulation. Here is one such coin I was lucky enough to find about 50 coins in. Even though I'm new to error hunting, I think this coin is exceptional for the following observations; 1. The 4 error marks in the obverse are RAISED. 2. All the marks have symmetry. 3. Flow lines for each mark can be seen from the liquidfication of the metal when the 4 negative impressions were pressed into the working die, from the hubbing process, or, when the raised marks were created in the planchet, from the coin stamping process. Which process that left these witness marks of the metal flow in the planchet are exclusive. It's one or the other, depending on the analysis of this error. In addition, the flow lines are symmetrical too. 4. You can see a die crack between the left side of the lower and upper corners of marks 2 and 3 respectively, counting from the top down. 5. This is a ONE-&-Done error coin. (So far). Does anyone recognize this error? Does this die error occur in the hubbing process? Here are some photos.       Help with recognizing this die error would be great. Do you believe it would be worth grading by NGC and would they give it a die error attribution? How would you ask for the attribution on the label? Regards Edited by stoystown_pa

Unfortunately its not a mint error, its a contact mark from another coin. No, do not have it graded.

 Just damage. PSD. Took a hit from another coin with its reeded edge. Errers and Varietys.

What he said. the marks were made by the reeded edge of another coin striking your coin, could have happened at any point after striking until it was pulled from the bag. What you see as a die crack was caused by the valley part of the other coin's reeded edge coming in contact with your coin. great camera work, by the way, what are you using?

Whatever it is (and it sure looks like PMD to me), those are some awesome pics! How did you manage to get them that crisp? |

Hi, Thanks for the feedback, but I have to admit I'm just a bit excited at this die error. Your comments provided me with a eureka moment, I have to say. I spent a long time trying to understand this error but just couldn't figure it out, that is until I saw your comments. Here's what I mean; Your right this is a edge of a 50C Kennedy 2020 D but it's not a PMD from being struck in the coin bag after it was struck. If that were so, the mark would be the opposite of a reeded edge of a 50C. But this mark is RAISED not incused as I see it, if it were a PMD from another coin's reeded edge in the bag. What you are seeing on Presidents Kennedy's neck is the pattern of a reeded 50C's edge! Hers's what I believed happened; A prior 50C being struck in the stamping machine got side ways somehow and didn't eject! But rather was in such an orientation that it "clashed" with the obverse working die and imprinted it with the incused design of a typical reeded edge of a Kennedy 50C coin. Then at some point the coin that clashed with the obverse working die ejected and then again at some point later, (or it could have been the very next coin), the clashed obverse die struck this coin's planchet and left the reeded edge pattern from the obverse die clash with the previous coin's reeded edge. That is what I believe you see in the positive on President Kennedy's neck! In other words, this die clash took a 2 step process for this error to have been created. Have I been staring at this error for too long? Or am I right? See photos;      Thanks again for the feed-back. Regards, |

Hi,
I want to respond to your questions. I use a DYNO - LIGHT EDGE. I'm still learning but recently I discovered a way to be more precise in the focus at all magnifications. That is the microscope has a manual fine resolution control using a mouse wheel. So you don't have to deal with the courser side focus that also shakes your focus when you touch the camera.
Sorry for the small font in my previous and this post. I'm having trouble with the font controls for some reason.
Regards,

A contact mark would be incuse, that looks raised. Is it?

You did say it was raised, so I don't think it can be a contact mark like suggested.

so are you saying that a struck coin was hard enough to cause these marks on a hardened steel die?

I am not sure what caused this but I think it would have had to have been on the die. How could another coin hitting this one leave a raised impression?

Hi, Sorry but I took a break to try and regroup my thoughts instead of just speculating what the process was that created these marks and risk just causing more confusion in this discussion if my speculation is incorrect. May I first say it is difficult thinking/visualizing in 3 dimensions. But such is the task here. There seems to be two thoughts from the coin community. One, coin drop - incused marks ( PMD). The other, no drop - raised marks (mint error). In order to try and advance this topic I just want to make an assumption and see if the photos agree with it or not and then go no further until there is a general consensus on that observation. Let's assume the coin drop, a bag mark, one coin falling onto this one, a PMD. So if you look at the edge photos you see the widest part of the "ridge" on the 50C's edge is at both ends. Both on the obverse side or the reverse side. The middle of the ridge is the narrowest part. Agreed. Now look at any photo of the marks. Hopefully you will see the the widest part of the ridge is flush to the surface of the INCUSED (assumed here) coin and the narrowest part of the ridge is at the deepest part of the incused mark. Do you see the problem with that? How can the narrowest part of the ridge(s) be the deepest/furthest from the surface if the narrowest part of the ridge is in the middle of the edge of the 50C dropped coin? If the coin was dropped, shouldn't the widest part of the ridge be the deepest and the narrowest part of the ridge break out to the surface, and therefore, at some point be flush with the surface? This is just the opposite of what the photos show. Therefore the coin drop - incused coin ( PMD) can be safely abandoned. All agree? Regards, Edited by stoystown_pa

Hi,
Bye the bye. The die being hardened is a good observation.
