From 1968 to 1998 all proof sets contained five or six coins in just one case. Then the enormously popular State quarter series began in 1999. Sets were expanded to include commemorative quarters which were housed in their own case. As the Mint added other commemorative coins — pennies, nickels and small dollars to their distribution, the size and scope of proof sets grew.
Our inclusive modern proof set collection includes every S-Mint proof set from 1999 to 2019 all in official U.S. Mint packaging. These sets range from nine coins to a sizeable 18 coins! That's 21 sets and TWO FREE proof set storage boxes for one low price!
