Now I know absolutely nothing about the "Black Nickel". I have had this 1954D Jefferson for many years. I found it as I was organizing my accumulation. It is totally and evenly black over both sides and the rim. Comments and feedback would be welcome.
I am certainly no expert, but going out on a limb, I'd say no. Look at the high spot wear marks on the obverse and it appears that the nickel is showing through, so I'd say it was an environmentally damaged coin. I'm basing some of this on the fact that most of the improperly annealed nickels were mostly 1958 and 1959, although it could occur on almost any date, and looking at environmental damaged nickels that have turned dark, or even copper colored. @paddyman98 might give a better answer. Mine:
Thanks @Mountain Man I appreciate the feedback. I saw that high spot too, but, like I said I have zero knowledge of these.
The edge needs to be clean. That's one of the markers. Since your edge has the same toning as the rest of the coin, etc.
If you mean a black beauty then no. The black beauties were improperly annealed. The planchets were over cooked so they look black. When they go through the (rim upset mill?) that's why their edges are clean. A regular nickel color as opposed to being dark. Your edges are the same color as the coin.
Hi I got one that fit that exact description. Dark front & back and simi clean edges & Mines a 1954 D. I don’t know how to upload a pic though.
