I would say XF but there is a good amount of wear on it so possibly say a VF35. The color might be caused by a previous cleanings
Personally, I'd prefer to keep it in the same old holder. In hand it looks quite a bit darker than the pics...less of the cleaned look. Probably an old light cleaning that has toned over well. In hand it appears to have darker brown colored fields and devices. Pics make it look a lot worse than it is.
I bet one of the TPG’s would give it a 45, or at least XF/cleaning. Not that the looks of the Coin bother me, but it might bother them (from the photos). I love it!
