The Fifty-State Bicentennial Medal Collection - Proof Set-52 oz Sterling Silver! It contains 50 state medals in proof condition- encased in acrylic and enclosed within a book. The design of the medals were from 50 different award-winning artists (one per state).... There are five pages of 10 coins each-each separated by a double page paper insert. Each coin weighs 1.0416 Troy Ounces of Solid Sterling Silver for a total of 52.08 Troy Ounces.There were 32,760 of these sets minted. On a personal note, this is one of many sets of coins and ingots collected by my father. He kept a piece of cardboard folded around the pages to keep the shape in tact. However, it did cause some discoloration on the first page only. Please see my other listings for additional proof sets and collectibles.
