Proof 1841 Half Dimes are very rare. Estimates of the number of survivors range from five to twenty examples. We've been able to identify six demonstrably different examples, thus it is reasonable to assume that as many as ten Proof 1841 Dimes exist today. The finest examples are a pair of NGC PR65's: one from the Pittman and Kaufman Collection and another from the Eugene Gardner Collection (based on prior sales records, the market prefers the Gardner example as the more desirable of the two).
It seems that all proof 1841 Half Dimes are of the same die variety (V-1). Most are brilliant Proofs, though at least one has been called a Cameo Proof.
