2016-S Theodore Roosevelt, Silver Proof

Joel Iskowitz's Theodore Roosevelt reverse for the 2016-S Silver Proof places a young Roosevelt on horseback above the eroded badlands of western North Dakota, the country where the future president ranched at Maltese Cross and Elkhorn between 1883 and 1886 and developed the conservation views he later carried into the Antiquities Act and the National Park system. San Francisco struck 481,140 pieces for the 2016 Silver Proof Set, the figure matching the year's Silver Proof Set sales total because the five quarters shipped as a packaged product. The composition is the 90% silver, 10% copper alloy the Mint had used for silver proof quarters since 1992, on a 6.25-gram planchet carrying .1808 troy ounces of pure silver across a 24.26-millimeter diameter with reeded edge. The issue is the third of five 2016 silver releases and the 34th of the 56-design ATB program.

Authentication on the issue starts with weight. The 6.25-gram silver planchet against the 5.67-gram clad sister gives a calibrated scale a half-gram spread to resolve, the easiest non-destructive separation between the two products. The reeded edge reads as a uniform silver-gray band rather than the reddish copper-core line visible on a clad piece. PCGS, the Professional Coin Grading Service, and NGC, the Numismatic Guaranty Company, attach a Silver or S/Ag attribution to the slab insert alongside the proof grade and a Cameo (CAM) or Deep Cameo (DCAM) contrast designation, where DCAM is the standard outcome on modern San Francisco silver proofs because the working dies receive chemical etching before each press run. Strike diagnostics on the equestrian composition sit at the horse's musculature, the rider's silhouette against the sky, and the layered erosion bands in the badland buttes behind them. Population counts at PR70-DCAM run into the thousands.

The collector market positions the issue as a 2016 silver-set component priced against the silver-spot floor plus a slab fee. PR69-DCAM examples move at a modest premium over the bullion value carried by the 0.1808 ounce silver content, and PR70-DCAM examples sit a tier higher with registry-set buyers driving the spread. The equestrian composition gives the issue cross-disciplinary appeal to presidential-coinage collectors and North Dakota state-coinage collectors that the natural-feature designs in the same year do not generate. The 481,140 silver print run sits at roughly 44 percent of the 1.09-million 2016 clad-proof figure, giving the silver issue a 2.3-to-1 scarcity ratio against its clad sibling.
