Thoughts on this eBay seller?
As a toned Lincoln cent collector, I noticed a certain eBay seller by the name "mikesmountainvalues", who I'm sure some of you have seen before as well. He auctions dozens of toned BN Lincoln cents every week, all graded by NGC. What I find concerning is that they all appear to me artificially toned, yet they still straight graded. I attached a screenshot below, as well as a link to his store. If they were all to cross to PCGS, the BN Lincoln cent pop reports would be completely ruined (but that's the point, they wouldn't straight grade, because they all seem to be AT).
Do you agree that they are artificial? Shouldn't NGC do something about this?
