Seated dollars in MS63 ????????

Opinions? They are a middling grade, but seem not to be around much. Seems more should be around than higher grades, but not the case as I see. Higher pops than the higher grades. Where are they?

For a type collector that above mentioned 1859-O and 1860-O are the most available dates. BUT even among those coins, many of them are bag marked to death.
A great looking Seated Dollar is a very tough coin. I guess that's why I overpaid for this PCGS PR-63, Cameo.
That goes for most Proof-63 Seated Dollars too. They are usually dipped to death.
