This 1993 Finest Promos Don Mattingly Refractor is on the top of all Mattingly enthusiasts wish lists. Pop4 with only one graded higher, this extremely rare card is not often found and only 7 have ever been graded, in any grade. This outstanding card is part of a set break from the previous #1 All-Time Don Mattingly PSA Graded Master Collection. Shown for reference is the award that accompanied the set (award not included).
