1940

Philadelphia struck 65,361,827 Mercury Dimes in 1940 as the country continued its industrial expansion in the run-up to direct involvement in World War II. The mint was operating at a brisk pace to keep pace with rising commercial activity, and the dime saw heavy use across every corner of American daily life. These coins circulated alongside earlier dates through the war years and well into the 1960s, when changes in silver content began removing them from active commerce. Mint State survivors are abundant thanks to roll hoarding during the post-1965 silver speculation period, and the 1940 is one of the easier late-series dates to acquire in attractive condition.

The obverse shows a youthful Liberty wearing a winged cap, designed by Adolph A. Weinman, with LIBERTY around the rim and the date at the lower right of the truncation. The reverse carries a fasces with an axe head emerging at the top, diagonal banding from the thong wrapping the rods, and an olive branch curving around the base. The coin contains 90% silver and 10% copper, weighs 2.5 grams, measures 17.9 mm, and has a reeded edge. Strikes on 1940 Philadelphia dimes are typically strong, and Full Bands examples appear in roll quantities. Authenticators verify the date positioning, the depth of the wing feathers on Liberty's cap, and the central bands on the fasces for the complete horizontal separation required for the PCGS or NGC Full Bands designation.

The 1940 is affordable through MS-66 Full Bands and remains within reach for most series builders even at MS-67. Heritage Auctions records show strong but not record-breaking results for high-grade pieces. Buyers should match expected prices against current Heritage Auctions and Stack's Bowers Galleries records before committing to a purchase. Collectors building a date-and-mintmark set should keep an eye on registry-set premiums when assessing comparable certified examples. The Mercury Dime series history fills in the broader picture.
