2017-S Sequoyah Proof

San Francisco's 2017 Sequoyah proof presents a portrait of a man whose work belongs in the same conceptual class as Cyrillic, Hangul, or N'Ko: a writing system invented by one person for a language that previously had no script. Sequoyah, a Cherokee silversmith born around 1770, completed his syllabary around 1821, and within a few years tens of thousands of Cherokee could read and write in their own language. The reverse, designed by Chris Costello and sculpted by Charles L. Vickers, places Sequoyah at a tablet with characters from his syllabary across the field and his name rendered in those same characters along the rim. The proof finish carries the design well: the mirrored fields throw the frosted devices into high relief, and the small syllabary letterforms read sharply on a struck-twice planchet in a way they cannot on a single-strike business piece.

What collectors look for on this proof is uniformity of finish and the depth of the cameo contrast. Cameo, the strong contrast between mirrored fields and frosted devices, is standard on modern San Francisco proofs, and Deep Cameo (PCGS) or Ultra Cameo (NGC) designations track the heaviest frost on the central design elements. PR69 and PR70 dominate certified populations because the coin shipped from the Mint inside sealed plastic capsules within the 2017 Proof Set and the various themed sets that included it. The 1,249,845 mintage covers all proof sets containing the Sequoyah dollar combined; identifying the coin as the Sequoyah issue rather than a different year's design is straightforward thanks to the dated edge lettering. No counterfeits are a working concern at this date.

Inside the collecting landscape today, the 2017-S is a common modern proof whose role is set completion rather than rarity acquisition. PR69 Deep Cameo examples trade in the low single digits and PR70 examples carry the typical perfect-grade premium.
