    Important 10-Piece 1870 Proof Set Featuring
    Singular PR67 Cameo Quarter

    10-Piece 1870 Proof Set. The Philadelphia Mint produced 1,000 proofs of each silver denomination in 1870, and most were distributed in silver and minor proof sets of the year, although an unknown quantity may have been melted at a later date. In fact, the surviving population of all silver denominations is comparable to the issues of the late 1860s and the following few years, most which have considerably lower proof mintages.
    It seems logical that the number of proofs coined in 1870 was much greater than the number of sets actually sold, with the balance melted over the next few years. Alternatively, delivery of small quantities of proof coins throughout the year would indicate a continuous demand for those coins.
    An additional quantity of minor proof sets may have been coined, although the likely excess of silver coins may mean that no additional minor coins were needed. All attempts to correlate current population data and original mintage estimates have been unsuccessful. Aside from a few minor date recuttings, there are no significant proof varieties for 1870. However, early and late states of the same die marriage are noted on some issues.

    Cent PR64 Red and Brown NGC. Both sides show copper-gold fire and cooler lavender-blue color, but in different mixtures. The obverse has a broad copper-gold center edged in the lavender-blue, but on the reverse, an interior wedge of the latter color floats in a sea of the former.

    Two Cent PR64 Brown PCGS. Deep old-copper color with rose-plum overtones. A sharply struck near-Gem with generally smooth surfaces, though scattered hairlines and faint contact preclude a finer designation.

    Three Cent Silver PR66 Cameo NGC. Violet and gold peripheral tints give way to virtually untoned centers where frosted devices contrast with the gleaming fields. A sharp Premium Gem that shows a small planchet flaw just to the right of the lowest arm of the star.

    Three Cent Nickel PR64 NGC. Moderately reflective nickel-white surfaces offer faint contrast with satiny, softly struck devices. Liberty's portrait shows a diagonal graze, and the fields show a handful of hairlines.

    Five Cent Nickel PR65 Cameo NGC. Aside from faint golden tints, the only patina on this Cameo Gem is a small, cloudy spot between the two rightmost bars in the shield. Sharply struck and pleasingly preserved.

    Half Dime PR63 NGC. Minor hairlines through the obverse fields define the technical grade, but reflectivity and peripheral gold-orange toning are key to the eye appeal. Well-defined devices are mildly frosted.

    Dime PR65 Cameo NGC. The obverse coloration is similar to the half dime's but with the addition of blue. The reverse is silver-white almost completely. Both sides offer thickly frosted devices and excellent contrast.

    Quarter PR67 Cameo NGC. Truly a coin to celebrate; it is the single-finest Cameo specimen found in the NGC Census Report (11/09). The immensely reflective obverse has subtle mauve and gold peripheral tints, with the former color deepening to violet-blue on the reverse. Outstanding contrast and preservation lead to incredible visual appeal.

    Half PR64 NGC. Dusky blue-violet and pearl-gray shadings dominate the obverse, while the reverse shows green-gold, silver-gray, and sage toning. Both the frost on Liberty and the reverse's considerable contrast hint at a coin that once would have qualified as Cameo.

    Seated Dollar PR63 NGC. Charming turquoise and champagne patina embraces the shining surfaces of this Select proof. Though lightly hairlined, this sharp specimen remains immensely appealing.
