2007-S Idaho, Silver Proof

2026-03-09, San Francisco struck 1,313,481 Idaho silver proofs in 2007 for the year's Silver Proof Set, the collector-tier companion to the clad proof. Don Everhart's reverse places a peregrine falcon, Idaho's state raptor, in profile across the foreground, its body and folded wing detailed in frosted relief and its talons gripping the upper edge of an outlined map of the state. The Latin motto "Esto Perpetua" runs as the design's only inscription beyond the state name and date. On a 90% silver planchet, the layered feathers along the falcon's wing and the engraved border of the state outline gain a precision the copper-nickel clad cannot match, the bright white metal lending the bird-and-cartography pairing a clean, almost heraldic brightness against the deeply mirrored fields.

Authenticating a 2007-S Idaho 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 feather edges along the wing, the falcon's eye and beak, and the line of the state outline under angled light for the heavy frost contrast that defines a properly struck silver proof.

None of the 2007 Idaho 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 peregrine falcon subject draws topical interest from raptor and conservation-themed collectors, the species' twentieth-century recovery from near-extinction makes the design an unusually loaded piece of wildlife iconography.
