About this coinHistory

The Denver Mint produced 22,674,800 Mercury Dimes in 1918, a healthy output that placed the issue alongside its Philadelphia counterpart in availability terms. Coins moved into circulation through Rocky Mountain commercial banks and reached the Midwest and Pacific Northwest in routine commerce. The wartime economy was running hot and small change saw heavy turnover, which kept circulated survivors abundant through every grade from Good to Extremely Fine. Mint State coins exist in reasonable numbers, but as with most Denver Mercury Dimes from this period, the survival pattern favors well-circulated material because collectors at the time concentrated on Philadelphia issues and rarely set aside branch-mint examples.

The D mintmark sits to the left of the fasces base. Authentication should verify mintmark font and position relative to nearby design elements, since added-D fakes appear occasionally on dates where Denver carries even a modest premium. Strike is the central conditional issue on the 1918-D. Many examples show flat central bands and softness in the wing feathers, making Full Bands (FB) examples notably tough. PCGS and NGC define FB as full separation of the two horizontal bands across the middle of the fasces, and on this date the qualifying population is small relative to overall Mint State numbers. Original luster, even rim quality, and clean fields are the marks of a strong example; avoid coins with retoning that masks light cleaning.

Pricing in circulated grades is modest, but Full-Bands examples climb quickly through Mint State and command serious premiums at the gem level. Heritage Auctions and Stack's Bowers have realized strong results for high-end FB pieces, and population data confirms how thin the supply becomes above MS65 FB. Population reports updated regularly by Professional Coin Grading Service and Numismatic Guaranty Company give the best read on conditional scarcity by grade. The Mercury Dime series history documents strike characteristics by date and helps frame expectations for set builders.
