The Dansco album (#8166) has been taped on the first page only in order to prevent the coins from falling out (see pix). The missing coins are the 1979-S and 1981-S Proof Variety 2 and 1991-S Proof. All silver coins are included and all coins are Brilliant Uncirculated or Proof! This set is Nice! The item “1964-1991 P, D, S Kennedy Half Dollar Set in Dansco Album 76 Coins Proof & Silver” is in sale since Saturday, July 17, 2021.
