1947-S

The 1947-S quarter is the low-mintage member of the 1947 trio, with the San Francisco Mint striking 5,532,000 pieces against 22.5 million from Philadelphia and 15.3 million from Denver. The figure is roughly a quarter of the Philadelphia total and noticeably less than San Francisco's wartime output, reflecting the Treasury's general scaling-back of West Coast quarter production once defense-industry payrolls in the Bay Area shrank. The S mintmark on this issue sits on the reverse below the wreath, the standard placement for San Francisco quarters from 1932 through 1964. The coin is not currently classified as a Semi-Key on the site, but its mintage puts it among the lower-output Washington quarters of the postwar decade.

Strike on the 1947-S is generally crisp, with San Francisco quarters of this vintage often showing better device definition than their Denver and Philadelphia counterparts. The mintmark deserves close inspection under five-to-ten-power magnification for any underlying letter trace, since the S punch was reused across many years and over-mintmark mishaps elsewhere in the series prove the die shop occasionally mixed punches. Counterfeit alteration is the primary authentication concern: a common 1947 Philadelphia coin can be doctored to look like a 1947-S, and tooling marks around the punch base are the giveaway. Population reports at PCGS, the Professional Coin Grading Service, show the date is reasonably well-represented through MS65, with the meaningful condition pressure appearing at MS66 and above where original surfaces and full luster both matter for registry purposes.

The lower mintage keeps the issue more interesting than the typical postwar date even at its current Regular classification. Circulated examples trade for modest premiums over silver melt, and Mint State coins through MS65 are obtainable without much hunting. Toning specialists pay up for original-skin examples with attractive peripheral color, since San Francisco quarters of this era often developed pleasing rainbow or sea-green patina before the dipping cycle removed most of it from the market. Realistic acquisition for serious collectors is a certified MS66 from a major auction, with the upgrade path running into real resistance at MS67.
