Does NNC grade problem coins?
Per our Terms and Conditions for those submitting coins to be graded: LIMITATIONS ON GRADING SERVICES. NNC will not issue a grade for any coins of questionable authenticity. Problem coins will be graded if the problem is not too severe and the problem can be easily described, i.e. “MS-63 cleaned”, “MS-62 scratch obverse (or reverse)” etc. For multiple problem coins, only the most obvious problem will be identified on the labeling of the coin. The customer understands that in such an event NNC will not refund any fee paid for the grading service. We will not, however, grade a coin which has been “whizzed” or “scratched and repaired”, those coins will be returned ungraded and unslabbed to the customer and the grading fee, minus return shipping and insurance fees, for a coin so identified will be refunded.
