I wouldn't buy it unless it was authenticated.

To give you a hint, the sellers name could also be read as "coin sand paper"

Just looks like a cast counterfeit.

the ONLY thing that could dissolve gold was an acid called Aqua Regia That is true for pure 24kt gold but classic gold coinage is 10% copper so it is subject to a certain level of corrosive action. |

I think you're probably right silverstackerkid http://coinsweekly.com/en/Archive/8?&id=13&type=aPocking like this might come from heavy overplating but a really really bad casting is more likely. A lot of jewelry and buttons are made with cast replicas, this is probably the same deal. "Two minutes ago I would have sold my chances for a tired dime." Fred Astaire

Aqua Regia is a combination of one part nitric acid and three parts hydrochloric acid. The former is capable of dissolving copper, but the latter is not and I can't see a proper alloy mix being selectively dissolved in this fashion. I'd be surprised if this coin is gold.

It looks cast to me. And not very well done either.

If only one side was porous (the side making contact with the wearers skin) there might be a SLIGHT chance that it could be legit. Even dug coins seems to have one side in better better than the other. In the watch world gold plated watches (usually very little to no gold over brass or base metal cases) use stainless steel backs as that is the surface that makes most contact with the skin. You will find cases that are totally eroded but the SS case back is 100% intact. I had one that was disproportionately eroded and one plausible case was that the person who owned it must have had a heart condition and the nitric acid due to their prescription. http://www.network54.com/Forum/7844...>%3B>%3B |

IMHO - if this was a exjewelry piece, I would expect it to be over polished, not pitted... I don't know if it is a poor cast or made from spark erosion dies... It has been many years since I seen a photo of a spark erosion coin and don't remember the exact type of finnish... It may have been a old/antique Coin World Anacs Article of fake Morgans... |

If it's genuine, perhaps it was a salt water salvage.

Salt water wouldn't do that kind of damage but the scouring of the sand could.

 It looks like a terrible attempt at casting a counterfeit. |
