2012-S Benjamin Harrison Proof

San Francisco struck 1,438,858 proof Benjamin Harrison dollars in 2012, the third design in the four-coin proof set after Chester Arthur and Grover Cleveland's first term, with Cleveland's second term closing the program calendar that November. The figure marks a sharp drop from the 2,809,452 produced for each 2009 design and the 2,224,613 for each 2010 design, continuing the steady decline in collector-set sales that ran through the program's later years. Buyers received the Harrison proof packaged either in the four-coin Presidential Dollar Proof Set or in the larger fourteen-coin annual Proof Set sold by the United States Mint. Phebe Hemphill designed and sculpted the obverse portrait of the 23rd president, paired with Don Everhart's Statue of Liberty reverse used on every business-strike and proof Presidential Dollar across the series.

San Francisco proof Presidential Dollars are struck twice on polished planchets with frosted dies, producing the contrast between mirrored fields and frosted devices known as Cameo. The standard expectation on a 2012-S Harrison is Deep Cameo, the strongest grade of contrast, abbreviated DCAM by PCGS, the Professional Coin Grading Service, and Ultra Cameo, abbreviated UCAM by NGC, the Numismatic Guaranty Company. Coins falling short of those designations are uncommon enough that they trade at a small discount rather than a premium. The grade ceiling sits at PR70 DCAM, where microscopic field marks around Harrison's portrait, struck in slightly higher relief than the reverse, typically separate a 70 from a 69. Since proofs never circulated, the 69-versus-70 line is a question of surface fineness rather than design wear.

Collector use of this coin is straightforward. It fits into a complete 40-coin Presidential Dollar proof run, into a 2012-only four-coin proof set alongside Arthur and the two Cleveland terms, or into a single-design Harrison three-coin set with the Philadelphia and Denver business strikes. Raw proofs from broken-up Mint sets remain inexpensive, and PR69 DCAM slabs trade for modest premiums; PR70 DCAM coins carry a meaningful step up but stay accessible compared with the 2007 first-year proofs.
