This is a group of 5 coins. All are NGC 1968-S proof Washington quarters with 30-90 degree rotated reverses. The coins are in varying degrees of rotation, and the exact amounts can be seen in the images.
A rare opportunity to own 5 proof proof rotated dies, which all appear to be from the same dies. 3 are perfect matches, while the other two are missing some die gouges in the eagle's (viewer) left wing. The other 2 do not have those gouges but have a design imperfect in the eagle's right wing.
NGC PF68 Ultra Cameo (the same grade on all 5 coins.)
