Just got this one back from grading, another purple holder. Do copper coins ever get successfully conserved with surfaces like this?
NGC and now PCGS have conservation services that I think charge 1% of the value of the coin. my local coin dealer just had a gold St gaugens with copper spots that he had PCGS conservation services take the copper spots off and give the coin its luster back... after all was done it gave another $2,000 value more to the coin...so it is definately worth the cost on more expensive coins you have. not sure what the value of your coin is at this moment ?
I have had environmental damage silver coins, in the holder attesting to this fact, sent through NCS and had them come back as numerically graded. I dont know if anyone has had success with copper coins in this regard. Never say never.
Yeah and that is no different than sending a coin in one time and having it graded 64, sending it in again and having it graded 65. Or, sending one in a getting the harshly cleaned designation, sending it in again and having it graded. And yet other times the coin will be returned same as it was the first time. Point is, the TPGs are quite often inconsistent.
I showed the coin to Tom Keenan today, the Colonial and EAC expert. He said the coin just appeared dirty to him, not damaged; he recommended using petroleum jelly to dab on and expertly remove the surface issue. My guess is that NCS will punt when they do not want to take the risk or if there is too much work involved as with all the different metallic compositions; copper-nickel or bronze. Silver is different than gold which are substantially different than the cents, half cents and two cent coins. Definitely a tough area for those used to dealing in the silver and gold coins.
I don't feel the staining on the reverse will ever come off. The rest of the coin can probably be improved a bit but I'm not sure about using petroleum.
OK, thanks for your professional view of the matter. So this would not be a got shot at getting NCS to conserve, they would probably just send the coin back to me without working on it. They charge 1% to evaluate, and 5% to do the job, $20 minimum.
