2002-S Roosevelt Dime. Silver--Reverse Die Cap--Proof-67 Ultra Cameo (NGC).A fascinating error, and one of the rarest die caps that we have ever offered due to its having been struck from Proof dies. The reverse impression is razor sharp within the base of a shallow cap, the planchet freeing itself (or being removed) from the reverse die after only a few additional impressions (likely one or two). The other side of this cap also exhibits a razor sharp strike, from the obverse die. Both sides are brilliant with deeply reflective fields supporting frosty design elements. While we are pleased to be offering several major Mint errors involving modern Proof coins in this sale, all are rare in an absolute sense since the Mints heightened quality control for these specially prepared coins means that few errors were produced, and even fewer escaped detection.
