I don't come across these very often. So I figured I'd post it and maybe get lucky lol. Looks like there is some copper showing. Any chance of missing a copper layer or just got stripped from some type of chemical?
The copper on yours was removed after it left the mint. Compare the as struck surfaces of the slabbed coin to the roughness of yours. PMD
Thanks Expat and Oldhoopster. I will mark it as PMD. I will keep it as a reference. Just might run into another and definitely do a comparison.
