2013-S William McKinley Proof

San Francisco struck 1,503,032 proof William McKinley dollars in 2013, the first design in the four-coin proof set ahead of Theodore Roosevelt, William Howard Taft, and Woodrow Wilson. The figure tracks just above the 1,438,858 produced for each 2012 design, continuing the steady decline in collector-set sales that ran through the program's later years. McKinley was the last Civil War veteran to serve as president, having enlisted at 18 with the 23rd Ohio Volunteer Infantry under future president Rutherford B. Hayes; the proof pairs naturally with the 2011-S Hayes proof in a small two-coin subset. Buyers received the McKinley 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, paired with Don Everhart's Statue of Liberty reverse used on every 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 2013-S McKinley 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 McKinley'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 2013-only four-coin proof set with Roosevelt, Taft, and Wilson, or into a McKinley three-coin set with the Philadelphia and Denver 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.
