2011-S Olympic Proof

The 2011-S Olympic Proof is the third design of San Francisco's second ATB proof year, struck against the 1,268,958-set production figure that anchors every 2011 clad proof issue. Susan Gamble's reverse renders a Roosevelt elk standing at the edge of the Hoh Rainforest with Mt. Olympus rising beyond a fringe of conifers, a composition that layers wildlife, temperate rainforest, and alpine peak into one register. The proof process suited the design well: polished fields throw the field mirror across the open sky behind the peak while the frosted devices carry heavy contrast on the elk's hide, the conifer foliage, and the mountain's snow detail. Olympic was protected as a national monument in 1909 under President Theodore Roosevelt and elevated to national park status by Congress in 1938.

Authentication on the issue starts with the S mintmark above Washington's head and the surface contrast that defines modern proof work. PCGS, the Professional Coin Grading Service, and NGC apply two cameo designations that drive most of the market value: Cameo (CAM), strong mirror-to-frost contrast, and Deep Cameo (DCAM), where the frost on the elk's antlers and the conifer detail is heavy and dense and the field mirror is unbroken. Look at the elk's antler tines and the texture across the rainforest understory for strike grading. The composition is among the busier 2011 reverses, which gives strike sharpness more visible weight at higher grades than the simpler 2010 designs. 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 on the modern alloy is functionally zero.

As a collecting target, this is a Regular-classification issue widely available in PR69-DCAM across both major services and steadily supplied in PR70-DCAM at a workable premium. Pop reports for the date show standard distribution, with the real climb at PR70-DCAM rather than at the Deep Cameo break. The piece draws a modest extra demand bump from Pacific Northwest regional collectors and from wildlife-design specialists who pair the issue with the 2011-S Glacier proof for the year's two animal-driven reverses.
