2015-S Blue Ridge Parkway, Silver Proof

San Francisco struck 472,828 pieces of the 2015-S Blue Ridge Parkway silver proof for that year's Silver Proof Set, the figure matching U.S. Mint product-sales records for the 2015 silver-set distribution. The coin is the third of five 2015 designs and lands in the steady high-470-thousand band that defined the 2015 silver-proof run, between the 2013 467,961-piece figure and the 2014 490,712-piece figure. Frank Morris's reverse depicts a Carolina northern flying squirrel (Glaucomys sabrinus coloratus) gliding among the rhododendron blooms of the parkway's high-elevation sections in western North Carolina, with the membrane stretched between extended limbs and the tail acting as a rudder. The 90% silver composition (.1808 troy ounces of pure silver inside a 6.25-gram quarter at 24.26 millimeters with a reeded edge) is the pre-2019 standard ATB silver-proof alloy.

Authentication on the coin anchors on weight and edge appearance. A calibrated jeweler's scale resolves the 6.25-gram silver reading against the 5.67-gram clad-proof reading without ambiguity, and the edge reads as a uniform silver-gray reeded band rather than the copper-nickel-and-copper-core sandwich a clad proof shows. PCGS and NGC apply a "Silver" attribution to the slab label on top of the numeric grade and Cameo or Deep Cameo contrast designation, where Cameo (CAM) marks moderate frosted-device contrast and Deep Cameo (DCAM) marks the higher-contrast tier and is the default outcome on the issue. Grade distribution clusters at PR69-DCAM and PR70-DCAM with population counts in the thousands at the top tier across both services. The design-specific diagnostic is the fine fur texture on the squirrel's stretched membrane and the individual rhododendron blooms framing the figure, both fine-relief elements that flatten under weak press pressure.

The coin trades in the modern silver-proof band with pricing that follows silver spot for most of its movement and a small set-completion premium on top. PR69-DCAM examples sell for a small step over melt plus slab cost, and PR70-DCAM examples in NGC or PCGS holders carry a modest tier above that. The 472,828 silver-proof print run is roughly 40 percent of the 1.18 million 2015 clad-proof figure for the same design, which gives the silver version a structural scarcity edge against the clad sibling. North Carolina regional collectors and endangered-species topical buyers provide modest crossover demand, since the Carolina northern subspecies has been federally listed since 1985.
