1860 Liberty Seated Dime. Proof-67 (PCGS).Delightful silver-olive patina dominates this coins outward appearance, direct lighting calling forth more vivid undertones of powder blue and champagne-pink iridescence. The devices are fully defined with a soft satin texture that contrasts minimally with well mirrored fields. The Mint had just begun marketing Proof coinage to collectors on a wider basis in 1860, and the mintage of 1,000 Proof dimes proved overly optimistic in light of actual sales. Several hundred of those coins failed to find buyers and were later placed into circulation, as was also done with many unsold Proofs dated 1859 and 1861. As a result, the Proof 1860 dime is much scarcer in todays market than the mintage might imply. This is an exceptionally well preserved and attractive Superb Gem that will please even the most discerning bidder.PCGS Population: 9; 0 finer in this category.
