1875 CC Twenty Cent Piece Questions

Looks genuine. Probably F-15. The surfaces don't look ofiginal, though.

Need much better photographs. Based on these pictures I would not buy it.

I am really bothered by the surfaces on this coin. The background and surrounding tells me that his lighting is ample and the white balance correct, meaning the coin's appearance is likely accurate and that's not the color one of these should be. I think that big black spot in front of the face is a hint.

It's not so much the dark color (kind of typical of circulated Seated stuff) as the nature of the color, and this is admittedly a more subjective than fact-based opinion. For something worth $300+ in this grade, this isn't the coin.
