2007-S Montana, Silver Proof

2026-02-08, San Francisco struck 1,313,481 Montana silver proofs in 2007 for the year's Silver Proof Set, the collector-tier companion to the clad proof. Don Everhart's reverse strips the composition to its essentials: a bleached bison skull, weathered and half-anatomical, set against the long horizontal sweep of the Rocky Mountain Front rising in the upper register. The inscription "Big Sky Country" anchors the scene below, with no other figurative element competing for attention. On a 90% silver planchet, the eye sockets and nasal cavity of the skull and the jagged ridgeline of the Front Range gain a precision the copper-nickel clad cannot match, the bright white metal turning the austere subject into something closer to memento mori than civic celebration.

Authenticating a 2007-S Montana Silver Proof begins at the scale. A genuine silver example weighs 6.25 grams against the 5.67-gram clad proof, and that 0.58-gram differential is the single most efficient diagnostic in the collector's toolkit. The 90% silver, 10% copper composition produces a silvery-white reflective surface noticeably brighter than the slightly grayer clad cast, and viewing the 24.3mm edge straight on reveals a solid silver color rather than the copper-cored sandwich stripe of clad coinage. Squared, sharp rims and heavily frosted Cameo or Deep Cameo devices set against deeply mirrored fields complete the visual signature. Examine the bone texture of the skull and the eroded ridgeline of the Front Range under angled light for the heavy frost contrast that defines a properly struck silver proof.

None of the 2007 Montana silver proofs entered circulation; all were sold through U.S. Mint Silver Proof Set packaging, and survival rates remain extremely high in pristine grades. Modern market value reflects both the silver bullion content and the proof finish, with Deep Cameo and PR70 examples carrying the strongest premiums. The bison-skull subject draws topical interest from western-state and minimalist-design collectors, who tend to pair the Montana issue with the 2008 Alaska grizzly and the 2006 Nebraska Chimney Rock for a coherent run of austere frontier imagery on the silver tier.
