Here’s an interesting one. At first glance when I got this back in my change, I figured it was damaged by some abrasion like dragged against cement, sandpaper, file,etc. However, closer inspection seems to look like it is something other than those formed of PMD. The very edge of the coin isn’t damaged along with the letters in that immediate area on the reverse. Any ideas? Thanks
??? One will never know for sure, but it I wanted to try to make a copy, I would pull out my small Dremel grinding wheel.
I may be crazy but to me it looks like the area that the zinc is showing failed to get its copper coating. I css as n see the lines from what appears to be damage but if you look very closely those same lines got coated with copper further into the field.
Do you see in this screenshot how the damage is raised above the surface? This doesn't look like it was imparted by any grinder. And the way the letters rest up against it, it looks like this damage was there before the coin was struck. To me, anyway...
Could this be a type stiff collar abrasion as the blank was forced into the coining chamber? I note a bit of weakness on the obverse opposite the abrasion, which maybe a sign of the abrasion being pre-strike.
LOL, I hear ya. I'm always defaulting towards PMD on coins myself. But as mentioned above, the area in question is raised. Also if it were an PMD abrasion, it would have had to have been really remarkably done well as not to hit the very edge of the coin and the lettering, which are both raised areas as well. An odd one for sure.
I’ve come across a few of these when searching brand new shield cent boxes. 2022 and 2020. Also 2023. My theory the 2023 I’ve been searching seem to be struck a bit harder excessive striking pressure but so minor and the rim of the coin is extra shiny more prominent and then you have this affect with it. To me occurs when being ejected from the striking chamber due to it being slightly thicker (height of rim) in that area. It’s common I just see it as damage and not a type of error. A spender for sure
I retract everything I said previously to being a stiff collar. If so then we’d see zinc on the edge of the coin and missing copper plating. We’d also see a flange and weakness opposite that flange bc metal flow was going between the die neck and collar. For instance this 2021 stiff collar (forced misalignment) Bc if the coin was forced into the striking chamber being off set then we have the outside of the coin being affected not the rim. And when struck the rim of OP’s coin and zinc should be affected if it occurred when entering the striking chamber bc when struck the rim of the coin would be produced and we’d have the rim of the coin being seen thru the zinc. In OPs the rim is affected so what we r seeing couldn’t have occurred before the strike. I still settle on if occurring when being ejected from the striking chamber.
An update on this coin. I was able to flip a piece of that silver material upwards. So it's additional material, not removed material exposing the core of the coin. If you look at the pix of the rim, the very edge of the rim has copper on it. This material that I'm able to flip up is between the very edge of the coin and the lettering. I'll get pix of it and post it up on here later on today.
No what I'm saying is I was able to pull up a little of the silver zinc material that's between the rim and the lettering.
I just found this one and it reminded me of this thread. I'm going to start a separate thread but here is one pic.
