1916-S Mercury

San Francisco's 1916 contribution to the new Mercury Dime design totaled 10,450,000 pieces, a moderate output that placed the issue squarely in the regular-date category from day one. The branch mint had been striking Barber Dimes earlier in the year, and the changeover to Weinman's design happened later in the production cycle. Coins entered circulation across the western states, where they joined the heavy small-change flow tied to wartime industrial pay packets and consumer goods. Survival was reasonably good in circulated grades because savers tucked away first-year pieces from each mint, but Mint State material thinned out by the late 1920s as the saved rolls were spent during economic downturns and the early Depression.

The reverse mintmark sits to the left of the fasces base, and on this issue the S punch tends to be small and slightly tilted, a detail useful when separating original pieces from added-mintmark counterfeits. Authentication on a 1916-S focuses on date style, the position and weight of the S, and a check that surfaces under the mintmark do not show tooling. Strike quality varies considerably; many examples show softness in the central bands and around Liberty's hair. The Full Bands (FB) designation, awarded by PCGS and NGC when the two horizontal bands across the middle of the fasces are fully separated, is achievable on this date but commands a multiple over standard Mint State pricing. Look for original luster and avoid coins that have been dipped to mask haze.

The 1916-S is a popular type coin and a logical companion to the Philadelphia first-year issue for set builders working a three-mint matrix. Heritage Auctions and Stack's Bowers regularly handle gem FB examples, and population data shows the date is more available in MS65 FB than several mid-series S issues.
