USA Grading Company

These type of companies have really damaged the hobby with new collectors. The newer collector has heard they should get a graded coin when they are not good at grading themselves and these type of basement slabbers depend on that to make money. These people are usually coin dealers themselves and just place their inventory into plastic holders that look like real TPG holders and target the unknowing collector because they see a grade on a plastic holder and think it was done by a third party not the actual person who owned the coin when it was placed in these holders. Dealers have been marking their inventory with inflated grades way before there were ever any TPG but since the TPG's have taken off in the hobby this is just another weapon in their arsenal to get over on new collectors. As Sap said above some of these coins are problem coins and some are even fakes and just about every time the coins have inflated grades to try and prey on the people that can not grade themselves to try and get more money for their coins. Even though this is nothing new with dealers it is more deceptive than just having a inflated grade on a cardboard 2x2 because it makes the collector think they are getting an unbiased opinion on grade when in fact it is no better than the grade would have been on the 2x2 of yesteryear

Coin World shell, no hologram, no barcode, no serial number. Almost certainly a self slabber, but it is odd in that case that they included an address on the back label. Not one I have seen before.

The coins are only worth what the coins are worth. Any grade claims made by the holder would be considered meaningless. They are, in the eyes of the market, raw coins. Would it be worthwhile submitting them to a reputable service? Only if you could be sure they would grade at the high grades listed on those holders. One way to estimate would be to assume a cost of $30 per coin for grading, shipping, and insurance and what they would be worth if they came back two grades lower. In of the words if the coin in a slab from a reputable firm graded two grades less than the grades on the current holder is greater than the cost of the coin plus $30, then it might be worthwhile to resubmit it. (This is assuming you don't have to pay another $50 to $200 to join up so you can make direct submissions. If you aren't going to be making a lot of submissions, and if you are you had better be able to grade yourself, it would probably be better to submit through an authorized dealer.)
