1940-D

Denver delivered 21,198,000 Mercury Dimes in 1940, a healthy figure that places this issue among the more accessible late-series Denver coins. The dimes entered circulation throughout the Mountain West and points east, where they passed through the rapidly expanding wartime economy of the early 1940s. By the time silver content changed in 1965, many of these coins had logged 25 years of pocket time and showed it. Roll hoards preserved Mint State examples in adequate quantities, however, and collectors today have little trouble finding the date through MS-66, though Full Bands quality requires more searching than the raw mintage suggests.

Liberty appears on the obverse in Weinman's winged cap design, with the reverse carrying the fasces and olive branch motif. The D mintmark sits to the left of the fasces base on the reverse. The coin weighs 2.5 grams in 90% silver and 10% copper, measures 17.9 mm in diameter, and has a reeded edge. Authenticators check the D punch for the era-correct serifed style and verify the placement of the mintmark relative to the fasces base. The central bands on the fasces must show complete horizontal separation across the middle to qualify for the Full Bands designation from PCGS or NGC, and the 1940-D often comes with one or both bands fused or weak. Wing detail and the date depth also reveal strike strength.

The 1940-D is reasonably priced through MS-65 Full Bands, with the climb getting steeper at MS-66 FB and above. Stack's Bowers has recorded solid results for top examples. The date is a practical addition to any set. Population reports updated regularly by Professional Coin Grading Service and Numismatic Guaranty Company give the best read on conditional scarcity by grade. Roll-quantity finds from estate consignments occasionally bring fresh material to the market, though such groups are increasingly uncommon. For broader context, see the Mercury Dime series history.
