thanks for all the great replies
in hand sight seen this coin is totally original dove grey with absolutely no hairlines or cleaning underneath the original dove grey surfaces. from the surfaces with some cuts and circulation evidence you can tell by experience that this piece actually circulated and was not a pocket piece as a pocket piece with its distinctive wear would look totally different
now the 1870-cc
Seated dollar was the first coin struck at the new carson city mint in 1870 and most all where weakly struck with the reverses more strongly struck so this is why usually the reverses grade 4-8 points higher than the obverses
pcgs gave this coin a vg10 and I cant really complain but for me it is almost a fine and with its original surfaces and great eye appeal being so clean and beautiful color which is highly unusual for a large silver coin that has circulated down to fine or thereabouts
this again is really rare as usually coins fine and below are problematic just from being in circulation so long
for me this coin wqould sell for fine money and for me is obverdse 10+ reverse 12+ and with the original color and clean surfaces and great eye appeal pcgs in my opinion was conservative with their grade on this coin, but these coins struck at branch mints just do not really conform to the standard grading guides
but since these coins have an extremely high basil value I really do not mind this coin in a vg10 pcgs holder as then I can buy it for a few hundred dollars cheaper than if it was graded fine 12 or raw
but this is a good example where the holder actually hurts the value of this particular coin as out of the holder it can be sold for more

now a later date philly mint
Seated dollar that was originally strongly struck as opposed to a really weak strike of this 1870-cc when it was first made the later dagte philly mint
Seated dollar would be in a fine 15+ holder
but again with this 1870-cc dollar when it was struck it was fully struck on the reverse and low end au on the obverse so this is why you get this uneven wear pattern
so yes this coin actually is a fine 12+
