Just Environmental Damage. Here are some Metal Detected examples from my collection with different stages of environmental damage
That's quite a few, Mr. Ed. I did a bunch of metal detecting when I was a kid and I don't recall ever finding a dollar (maybe a half?). But Susan B's were brand-new and not many folks carrying Ikes in their pockets back then. I'm wondering if this is more a modern phenomenon given the change in size.
2000 was the first year of the Sac Dollar, and the Mint quickly had a problem with the finish turning a "puke" brownish-green color. It was determined that it was due to an improper rinse. Your coin looks a lot like those early coins. ~ Chris
Hmmm...reminds me of an old army drab plating I'd see on some fasteners. Puke brownish green hits the spot!
@paddyman98- Not to sway to far from the subject matter, just a slight detour. I'm really surprised to learn you (or anyone) could find so many MD'ing. I don't believe I've ever really seen them in circulation to any great extent, no less someone losing them on the beach. Maybe they were being used as a novelty when they first come out. Seems the mint has produced a few (probably billions) of business strike coins intended for circulation, that just aren't being used by the public. BTW: Nice find with those dollars!
Well gentleman as always thank you for your expert knowledge.i guess then i can try to clean it. Oh and heres another mystery for you i got this susan b huntchback coin in the same lot
