@windweaver77:
A few points of clarification:
1. NNC (National Numismatic Certification) is (was?) a lower-tier third-party grading (
TPG) service. It is not recognized as such by
ebay, and so coins in NNC holders can not be described as "graded" by a
TPG service. Many knowledgeable collectors question the grades assigned by NNC, so it is recommended that their assigned grades not be used to determine market value - gauge the coin itself. (Personally, I have seen over-, under- and accurately-graded coins in NNC holders.)
2. Why do some grade modern bullion coins? A few reasons:
a) Some collectors are more confident in the genuineness of a coin once it has been encapsulated by a reputable
TPG Service company. (Unfortunately, counterfeit slabs with counterfeit coins are now a part of the market.)
b) Some collectors strive for "the best" quality and so seek out "Pop Top" coins from a given
TPG Service. The PCGS and NGC Registries have fueled this drive with many collectors competing for the highest graded set.
c) Dealers grade them because they can market them at a premium (vs. bullion value) and know that many collectors will pay the premiums asked for the highest-graded coins. Though some question it, many collectors today collect
TPG Service labels - it's why many coins are encapsulated with a variety of different labels, the companies are casting as wide a net as possible.
In the video, the narrator (though he admits to being unfamiliar and inexperienced with the
TPG Service grading process) questions why someone would pay to grade a coin that has a market value less than the grading fees. One possibility is that the coin was submitted by a dealer as part of a bulk submission to reach a certain number of coins to qualify for a lower rate on all of the coins submitted. Another, the submission might have been free due to a special promo or coupon. I have personal knowledge of both situations.
Regarding ANACS grading fees, I'm not sure of the source of the "$50-70" figure mentioned above. A trip to the ANACS web site will provide accurate pricing information.
