I just noticed that the listing for the Bicentennial U.S. quarter has a listing for both the 1976-S silver non-proof and proof varieties, but that the pages for the half dollars and dollars only list a 1976-S proof, and not the non-proof varieties. Could these be added?
I double-checked, and my eyes aren't deceiving me; the Red Book and the HGC website list both varieties of the '76-s for each of these coins.
