I've found these hoard collections to be somewhat generously graded on occasion. I don't know if this one specifically, but the buy the coin, not the holder mantra certainly applies. Frankly, there are very few names on a label which would make me pay a premium. Eliasberg for example; I'd like to have one of his im my set at some point.
I am so picky. The "Granite Lady" is a nickname for the second San Francisco Mint which operated from 1874 to 1937. The coin in the advertisement is dated 1863, thus it was not made at the "Granite Lady".
From what I can find...these are a very large number of fairly nice "S" mint type 2 20s which have appeared in the last year or so. All I've seen, both on TV and at shows, and Apmex, etc. are in newer slabs. Many are priced just over spot and are plentiful, which is a good time to grab a few. I see them all over the place for $1375 on up for AU55 and 58 coins. Great for type gold sets and very affordable!
True, they are claiming they were stored in the vaults at the Granite Lady during the earthquake and fire of 1906. Exactly how you could prove that 110 years later I have no idea. They could be for a hoard stored anywhere, or assembled form coins brought back from overseas. Without some kind of really good documentation that comes with the coin it doesn't mean squat. The name on the label means nothing because bulk submitters can get anything put on the labels nowadays, just have to pay for it.
