2017-S George Rogers Clark Proof

San Francisco closed the 2017 ATB proof slate with Frank Morris's George Rogers Clark design at 1,078,981 pieces, the figure matching the U.S. Mint Clad Proof Set sales total because the five 2017 quarters shipped as a packaged product. The reverse depicts Clark and his Virginia militia crossing the flooded Wabash bottoms in February 1779 during the winter campaign that ended with the recapture of Fort Sackville at Vincennes from British forces. Clark is shown in foreground at chest-deep in the water, sword aloft, with men following behind. The design is the only winter-march composition in the 56-design ATB run. The issue is the fifth and final 2017 release and shares its design with the year's Enhanced Uncirculated counterpart, struck in the 225th-anniversary Enhanced Uncirculated Coin Set as a separate catalog entry.

Proof finish on the issue is the standard San Francisco style: mirrored fields struck from polished planchets against dies frosted in chemical baths before each press run, distinct from the laser-etched Enhanced Uncirculated finish on the related S-mint variant. Cameo (CAM) and Deep Cameo (DCAM) are the contrast designations PCGS, the Professional Coin Grading Service, and NGC, the Numismatic Guaranty Company, apply on top of the numeric grade, with DCAM the default outcome on the standard proof. The multi-figure historical composition makes strike quality the most diagnostic element: graders watch Clark's facial profile, the upraised sword, the surface texture of the floodwater across the field, and the figures trailing in the middle distance when separating PR69 from PR70. The clad composition (75% copper-nickel over a pure copper core, 5.67 grams, 24.26 mm) matches every Washington quarter struck since 1965, so counterfeit risk is essentially nil at the issue's price point.

The issue trades at the upper end of the lower price band among 2017 ATB proofs because the Revolutionary War subject and the dramatic winter-crossing composition together draw cross-disciplinary interest from frontier-history, military, and Indiana state collectors. A raw certified PR69-DCAM example moves for a small premium over the cost of breaking up a sealed 2017 Clad Proof Set, and PR70-DCAM examples in NGC or PCGS holders sit at a modestly higher tier above that. Finish-aware collectors building a complete 2017 George Rogers Clark run typically need both the standard clad proof and the Enhanced Uncirculated catalog entry, which is the structural reason the issue pairs across two distinct San Francisco products that year.
