I recently found this. I'm wondering if it's an annealing error or just stained. It's usually easy to spot a dirty or stained coin but this one has me scratching my head. On this one the grayish color is pretty uniform and still has a little bit of luster (in case you can't tell from the pictures). Would like to hear some opinions from those more knowledgeable than myself. As usual I appreciate it.
Okay. I appreciate it. I really thought I had something. Oh, well. You win some, you lose some. I'll still hold onto it for future reference.
It’s nice to have a few coins that look like yours. You may want to put them in a 2x2 and kept them. You only paid face value so no big loss.
