 If you spotted a UFO, you wouldn't go anywhere...

Quote:100% not PMD, merclover. I didn't think this through, you're right, it's not PMD, my bad. I was thinking of other times where we called PMD unknowns ufos. I was wrong, sorry. 
ça va bien aller

This was quite the discussion. It's part of the reason I enjoy this forum. People are so much alike and yet so often different with their opinions. Ranging from PMD, to die issue. From lathe markings to UFO. In the end I think you have a coin with issues that do not surface often enough for there to be one definitive explanation. Such as a RPM. So that initiates thought, and discussion, and debate, which only helps in our learning and understanding of what intrigues us in this hobby. Great post. Great responses. Cudos to Merclover for her acknowledging an oversight and her apology in the post. Thanks all. |

Ok , I have done a little turning on a wood lathe but I've never used a metal lathe. That said , when you want to center some stock on a lathe you can drill a small hole in the end of your stock where you want center to be and fit it over a centering tool like this  At any point the stock can be remounted on the lathe using this point and hole combo. It sorta makes sense that if a coned shape piece of die stock needed to be remounted in a lathe the point of the stock would be fitted into a small hole to center it. Tighten the metal stock on the lathe and you have nice little circle impression at the center tip of the die cone that leaves a circle on the final coins. Food for thought |

Your scenario may have some merit. However, the rings vary quite a bit in size and are often not perfectly centered. While some form a smooth circle or semicircle, others are somewhat irregular or have irregular features extending from the main ring. Paired, concentric rings are sometimes seen. Given their variability, it's entirely possible that these die rings stem from more than one cause.

Whatever caused them, I still keep mine. There are several known years and denominations but compared to other varieties/errors, they are quite scarce. Since searching coins and these being "a thing" I found maybe 4 and my last one was in 2020
