2007-D Washington, Satin Finish Proof

The 2007-D Washington Satin Finish Proof represents Denver's contribution to that year's Annual Uncirculated Coin Set, paired one-for-one with the Philadelphia issue inside every subscription package. Charles L. Vickers' reverse design pairs a leaping king salmon with Mount Rainier in the distance, the state legend "The Evergreen State" arched above the scene and "1889", Washington's statehood year, anchoring the lower field. The design was released into general circulation on April 2, 2007, the second of five Western quarters issued that year; satin examples are the Denver Mint's collector twin of the same composition, distributed only through the Mint Set channel rather than through banks. The salmon's gill detail and the geometric snow lines on Rainier sit under a uniform matte sheen under satin striking, the surface treatment that defines the format and separates it from both circulation and proof production.

Authentication begins at surface texture. Genuine satin specimens present an even matte finish across both fields and devices, the product of acid-etched or sandblasted dies rather than the polished-and-frosted dies used at San Francisco. There is no rotating cartwheel luster of the sort that travels across a roll-pulled Denver business strike when tilted, and no mirror-and-cameo contrast of the type that marks an S proof. Composition is standard cupronickel-clad, 91.67% copper / 8.33% nickel by total weight, with a 75/25 outer cladding over a pure copper core, at 5.67 grams and 24.3 millimeters, identical to the circulation specification. The D mintmark sits above Washington's queue on the obverse; no S satin variants exist, since San Francisco produced only mirrored proofs in this era. Third-party graders use SP (Specimen) or SMS designations rather than PR, a label distinction worth checking when sourcing certified examples. Per-mint mintage finished at 895,628 pieces for the 2007 set.

Because the coin never entered circulation, the as-struck Denver surface generally survives intact on examples recovered from sealed Mint Sets, and most certified pieces fall in the SP67 to SP69 band with SP70 examples appearing often enough to keep top-pop premiums modest.
