Didn't have one of these yet and I thought this one looked pretty nice for the grade. http://www.ebay.com/itm/1875-S-20-C...IOjkD%2FwuFnHt%2BNcJw%3D&orig_cvip=true&rt=nc
It doesn't look blast white or cleaned, and it appears that it may be attractive. The color in the photographs is strange, but I think that is a photography issue. I think it will probably be attractive in hand, but I hope you'll take better pictures and show us. So, tentative congratulations until I see better pictures, but I think you probably did well.
The 75 S most common I have one my self about the same condition . Price wise ya done good. Nice coin for your type set.
