Here’s an awesome error on a 2011 penny. You don’t see this on modern modern coins this extreme at all. “The fins are the result of abnormally high striking pressure (caused by either elevated ram pressure, reduced minimum die clearance, or both). That extra pressure makes the coin squeeze its metal into the narrow gap between the die neck and collar. The thin fragile fins were pushed inward after the coin was ejected.”
Very interesting,seems like you know what your talking about so I'll take your word for it. @paddyman98
This can also sometimes result from the same process that causes "dryer coins". I'm not sure which this is, but I am leaning toward the high pressure finning explanation. One problem you can have with such a high fin from a high pressure strike is that the coin tends to be wedged in place post strike by the fin trapped between the anvil die and the collar. This fin tends to get sheared off as the coin is shoved aside. The fact that only half the obv shows the fin is why I think this could be a finned coin. The rest of the fin on that side got sheared off.
Exactly and we can see that happened on the obverse 5-9ish. And the affects seen here can’t also happen from the process of a dryer coin. Looks “similar” not even close would be easy to tell a dryer coin from a finned rim error. But yea for an untrained eye new collector a little tircky.
Very interesting. Thank you for posting. Posting the photos FULL IMAGE would have been nice. I can see how this might have made it through the riddler. How did you come by it? CRH or purchase?
Yea I realized after now I can’t edit I wasn’t sure how this photo upload worked lol since I just joined CT. I’m used to coin community not as user friendly on mobile. Yea it was a purchase.
You may have seen this before, as I often post it, but it could be of help to you. For the best results, you should post "in focus," FULL IMAGE photos (after you upload your photo, two buttons appear: Thumbnail and Full Image, click Full Image and your photo appears full size on your post and are easily enlarged by clicking on it). Photograph coins on neutral backgrounds like black, grey, or white. Crop out superfluous background so just the coin shows (you can use https://www.remove.bg for free), and post photos with correct orientation so members don't have to turn their computer in some awkward fashion to view it properly. While it isn’t always necessary, it is nice to show both the obverse and reverse, even if your question is just about one side. Members can often give more valuable information having both sides to evaluate. Add close ups of areas you have questions about and make your questions as definitive as possible so we know what you are asking for. And try to have the best lighting possible to show the most favorable photo of the coin. Hope this helps in the future. Good luck
My other posts have full image I just didn’t know what those two options did at the time of this post
@paddyman98 Could that be considered a fold-Over-Strike? Very interesting error coin, in my opinion. Thanks for sharing.
I don't have any idea. How would the inner zinc come out after it was plated to Fin? Confusing. @JCro57 Please look at this coin.
Ah joe yea Had this posted in the Facebook group of his great guy. Id say tho that occurs when the metal squeezes between the die neck and collar and it comes off then. And then when ejected the fins are pushed inward bc they r thin and fragile. no evidence of a fold over strike
