| How to safely, naturally tone a coin
Bought this coin a year ago from Heritage and later decided I didn't want to collect graded coins (wanted them all stored in the same fashion). Later changed my mind and sent to NCS for conservation/evaluation and then to NGC. I stated on my invoice very explicitly that grading at NGC was priority over any conservation process (I now know through greater knowledge that these type of spots can't be removed). In all fairness to NCS, their customer service was excellent, and of the 9 coppers I sent in 6 graded (several would not have graded in my opinion without conservation and looked much better, but 3 looked worse, this coin one of them). The coin definitlely had no visible hairlines prior to sending to NCS. The removal of the toning showed the old hairlines. Consequently the coin is more unattractive now and UNGRADEABLE. My dilema is how to safely tone this coin to get it back to it's prior brown color, with the hairlines filled in by the toning. Then I will try and get it graded perhaps. I put the coin in an airtight and in a ziplock with rechargeable dessicant and Taco Bell napkin. I soaked in distilled water prior to being placed in airtight but checked the coin and it looked splotchy with wierd "dry" spots with film developing on coin. I then put mineral oil on coin and stored the way stated above and now it looks fine but don't know if it will tone with the mineral oil on it. I am nervous about safely toning this coin- don't want weird ugly stuff developing or verdigris.
