1917

The second year of Mercury Dime production saw Philadelphia push out 55,230,000 pieces, more than double the 1916 main-mint output. The country was edging toward entry into World War I, and small-change demand surged as wage levels rose in industrial centers. The Philadelphia Mint had refined its die preparation after the first-year learning curve, and 1917 dimes generally show better central detail than 1916 examples. They circulated widely and survive in large quantities through all circulated grades; Mint State coins are also reasonably plentiful, though true gems with original surfaces have thinned out over the decades as collectors chased upgrades and treasured pieces moved into long-term holdings.

The design follows Weinman's first-year layout: Liberty in a winged Phrygian cap on the obverse, fasces and olive branch on the reverse. Specifications remain 90% silver, 10% copper at 2.5 grams and 17.9 mm with a reeded edge. The 1917 Philadelphia carries no mintmark, so authentication issues center on date repunching and surface originality rather than added-mintmark fraud. The two horizontal bands across the middle of the fasces are the Full Bands (FB) target; PCGS and NGC will award the designation when both bands are fully separated. On this issue the strike is usually adequate but not exceptional, and FB examples bring a worthwhile premium. Watch for cleaned coins with broken luster and check the obverse rim for any signs of repair near the date.

This date is a workhorse type coin and one of the most affordable Mercury Dimes in higher grades. Heritage Auctions and Stack's Bowers list gem FB pieces frequently, and population reports show solid availability through MS66 FB before pricing climbs. For collectors building a date set, it pairs naturally with the 1917-D and 1917-S to complete the three-mint year. Background on Weinman and the series progression is covered in the Mercury Dime series history.
