    Extremely Rare 1968 No S Dime, PR68 Cameo

    1968 10C No S PR68 Cameo PCGS. The 1968 and 1975 No S proof dimes are arguably the rarest of all 20th century dimes. At first they resemble a Philadelphia coin, but proofs were not struck in that mint in 1968. The San Francisco Mint closed after 1955 and reopened in 1968 with proof coinage produced there. Occasionally proof coins are seen without a mintmark, and these pieces bring enormous premiums. More than 3 million proof dimes were struck in 1968, and in his 1988 reference Breen estimated that "about 6 (are) known." Since that time a few more have surfaced, but probably no more than 12-14 pieces are known today without the S mintmark. Only 16 pieces have been certified by the two major services both as non-cameo and cameo coins (no Deep Cameo pieces have been graded). In order to solve the No S problem, beginning in 1985 the Mint in Philadelphia placed the S mintmark on each year's master die for proofs. This has proved an effective deterrent as only one mintmark-free issue has occurred since (the 1990 No S cent).
    This is an outstanding example of this key issue. Brilliant throughout, the fields are deeply mirrored. The devices are lightly, but noticeably frosted, which provides a significant cameo contrast against the depth of reflectivity seen in the fields. This is a rare opportunity for the specialist to add this issue to a set of Roosevelt dimes; and, of course, such a high grade coin as this will be of interest to the Registry Set collector. Population: 3 in 68, 0 finer (8/06).(Registry values: P1)
