2015-S Bombay Hook Proof

San Francisco struck 1,177,515 pieces of the 2015-S Bombay Hook clad proof, the figure matching the U.S. Mint Clad Proof Set sales total because the five 2015 quarters shipped as a packaged product. Joel Iskowitz's reverse renders a great blue heron in the foreground of the Delaware coastal marsh with a great egret and a snow goose in the middle distance, all three species emblematic of the Bombay Hook National Wildlife Refuge along the Delaware Bay flyway. The composition layers three large birds across the field, a denser wildlife treatment than most ATB reverses attempt and one that puts unusual pressure on strike quality. The issue is the fourth of five 2015 releases and honors the only National Wildlife Refuge in the entire ATB program.

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. 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 rather than an upgrade tier. Grade distribution clusters at PR69-DCAM and PR70-DCAM with population counts in the thousands at the top. The diagnostic strike areas are the heron's individual neck and wing feathers and the wing detail on the snow goose at upper right, both fine-relief elements that flatten under weak press pressure into generic shapes. 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 routes through year-set or design-set assembly and trades in the lower band typical of modern clad proofs. A raw certified PR69-DCAM example moves for a small premium over the cost of breaking up a sealed 2015 Clad Proof Set, and PR70-DCAM examples in NGC or PCGS holders sit at a modestly higher tier. Bird-topical collectors and Atlantic-flyway enthusiasts treat the issue as a baseline acquisition, and the three-species composition has helped it draw slightly more cross-disciplinary attention than the typical landscape design. The 1.18 million print run reflects the proof-set sales decline that continued through 2016 and 2017 as the ATB program approached its second-half stretch.
