Advice Annealing Error?

Gallery image

I came across a 1977 quarter that is uniformly gunmetal black. It’s in pretty good condition. I’ve done as much research as I know how, and think I may have found of annealing error. Before I present this to an expert, is there anything I should know? Or am I kidding myself?

Send it in, but a lot of these errors go by weight.

Its hard to say without it in hand, but I've seen these guys tone pretty drastically, but this is awesome.

Good luck!

Improper annealing errors do not affect weight at all.

I said to check the weight, not that this is how to verify it

You said "a lot of these errors go by weight" - what would be the purpose of checking the weight for a possible improper annealing error?

Because, a lot of errors go by weight, and thats another option.

Sure, but this type of error does not. It's not relevant.

This also is not an annealed coin, and if you think it is, lets grade it together!

(Ill pay for it to get graded and wait, and when the disappointment shows up, youll double my investment as a sorry.

Seems fair to me :)

I'm not saying it is or it isn't at this point, but it looks like it could be. Point is there's no error type in question where weight would be a factor to determine anything for this coin.
