NNC National Numismatic Certification

NNC-NATIONAL NUMISMATIC CERTIFICATION

The company claims not to buy or sell coins and therefore is a true, independent, third party grader. My experience with NNC is their coins are graded a little higher than the accepted standard. Although, a careful buyer may find a suitable coin for regrade by the top tier graders.

No information on this grading company. Any TPGS without a website, address, phone number or email are usually "self-slabbers" who grade their own coins, sell them, and don't accept submissions from the general public. These companies are not recommended unless one can tell, first-hand, that the coin is authentic, problem free (not cleaned or damaged), and graded appropriately. If you have any information on this company send an email to help@coinauctionshelp.com
