This is a RARE collectible! Most of the issues are over 20,000...Going as far as 50,000 minted. Therefore, a few are more valuable as they have the fewest issues minted at 15,000. These include Truman, Eisenhower and Johnson. When opened, the display has two coins from the first day of issue from both the Philadelphia and Denver mints. The envelope is postmarked on that first day of issue. There is related historical information about each President (see the two Truman examples in the listing's photo's).
