Prethen Pillar of the Community United States 3234 Posts	Posted 01/07/2008 4:30 pm Look at the NGC U.S. Coins forum and check out the topic where 10 coins were processed with MS70. [This forum prevents me from creating a link to any "competing" forum.] This should be an eye opener for many of you here who have been asking how do you tell if copper is naturally or artificially toned. I'd bookmark that page! Report this Post to the Staff
