1859 Liberty Seated Quarter. Type II Reverse. Proof-66+ Cameo (PCGS). CAC. This is an interestingly and originally toned Gem, otherwise silver-tinged surfaces revealing a crescent of bold antique-copper patina over the upper and right reverse. A faint trace of similar color is also evident along the lower right obverse border. Fully struck throughout and expertly preserved in all regards, this amazing specimen ranks among the finest survivors of this scarce early Proof quarter issue. As with its identically dated half dime, dime, half dollar and silver dollar counterparts, the Proof 1859 quarter is far scarcer than a mintage of 800 pieces might imply. With many examples being released into circulation when they failed to sell to collectors, unmistakable Proof survivors are elusive. This is an exceptionally well preserved and aesthetically pleasing specimen that is far finer than most that we have handled over the years.
