Where there's one, there has to be more . Good luck on the hunt ... Here's an image with my Dino-lite ...
Here's a little write up . The distinctive black finish comes from an improperly handled annealing process. Annealing is the process of heating the planchet to ready it for striking. The planchets are then placed in a large furnace warmed by gas heaters to "relax" the metal. They are then passed through a washing solution to remove tarnish, which gives the planchets (coins) the familiar "BU" (Brilliant Uncirculated) finish.
I may be completely wrong in this statement. From the pics and error ref. Even the 58' 5c Black beauty. All the pics I have seen are either even colored black with no chance of toning, or, look like a lamination with Cooper coming to the surface. And the remaining nickel turning black. I am interested to see what @mikediamond. Has to say!
I used the cellphone for images, to show the luster in the fields ..... Dino-Lite, takes cartoon images .... Lol .....................
I understand the process but...... If it was not annealed properly, would that not make the metal brittle and cause it to fracture? It seems as though it is just the finishing with chemicals to remove the oxidized layer that may be the issue. As it does not give it that bright finish.
Rick, I agree with the ANACs one, but the coloration there is 'regular' across the fields. On the dime, it is not, more in a tarnished wear pattern, I think it is just environmental myself. Jim
My kid just got home and I'm going to try his cellphone for images, it's a brand new cellphone too ...
