Yep! Sandon is right and entirely realistic in cutting through the hyped nonsense.
Now, yes, Virginia, there is a "70" graded ('perfect as struck') Santa coin out there -- possibly several of them. But that identifier is meaningless, and has been since thief Sheldon cooked it up to explain large cent coin prices.
Coins kept in US Mint packaging can, for the most part, be as readily and accurately graded as ones removed and stuck in a TPG's plastic -- except you've spent an enormous percentage of purchase price on "paper 'n' plastic," and enjoyed the opportunity to introduce dirt, dust, spots, soda bubbles, and fungi to your prized coin.
Enjoy your coins and collect for that enjoyment. Anyway, the way TPGs are slipping grades, all your coins might soon be "MS-70."
