Centennial Series 2016

1916 was the year three new silver designs reached circulation: Adolph A. Weinman's Winged Liberty dime, better known as the Mercury dime, Hermon A. MacNeil's Standing Liberty quarter and Weinman's Walking Liberty half dollar. In 2016 the Mint marked the centennial by striking all three in .9999 fine gold at West Point, sized to its tenth-, quarter- and half-ounce gold planchets. The coins carry the date 2016, a W mint mark, their original denominations and the gold markings AU 24K with the weight, which the original coins never had.

The Mint called the finish a business strike. PCGS lists the coins as special strikes, and PCGS and NGC both grade them as specimens.

The dime was unavailable within an hour of release; the Mint later offered the coins left after order cancellations, one per household, for a final total 115 under the limit, per CoinWeek. Wikipedia gives the half dollar's maximum as 75,000; the Mint's figure reported by CoinNews at the time was 70,000.

In 2026 the Mint revisited the same three designs, plus two more, in its Best of the Mint gold coins. The silver originals are covered in the Mercury dime, Standing Liberty quarter and Walking Liberty half dollar guides.

• Date and markings. The 2016 coins read 2016 and carry AU 24K with 1/10 OZ, 1/4 OZ or 1/2 OZ. The 2026 Best of the Mint gold coins carry the original date 1916 and a Liberty Bell privy mark with the number 250.
• Size. Each gold coin is smaller than its silver original, the dime only slightly.
• W. The W is the West Point mint mark; the AW on the dime's obverse is Weinman's monogram.
