2015-D Kisatchie

Denver's 2015 Kisatchie production reached 213,200,000 pieces, running well below Philadelphia's 397,200,000 for the same design and showing one of the widest single-design mintage gaps between the two mints in the ATB run. The 184-million difference reflects the surge in eastern-region Federal Reserve demand that pulled Philadelphia output sharply higher across the 2015 lineup, while Denver continued at its more typical pace. Susan Gamble's reverse, the wild turkey in flight with longleaf pines anchoring the background, is the same composition used at Philadelphia and was struck from the same master dies. The Louisiana site choice was the program's only nod to a National Forest in the Gulf coast region.

Strike quality on the Denver issue tracks the broader 2015 Denver output: clean on the central bird figure through the early die states, with predictable softening on the wing feather detail and the pine-needle texture as dies aged. Graders concentrate on the turkey's wing contour and the pine cluster in the background when separating gem from near-gem. The clad composition (75% copper-nickel over a pure copper core, 5.67 grams total) matches every Washington quarter struck since 1965, and counterfeit risk is functionally nil for circulation-strike modern clad. The high-grade market runs through PCGS and NGC; raw examples in the MS65 to MS66 band remain easy to find in original Denver bank rolls.

This is a Regular-classification issue where the action sits at MS67 and above. Population counts thin sharply at MS68, with the Denver issue typically pricing alongside its much-higher-mintage Philadelphia counterpart in slabbed grades, since high-grade supply rather than headline mintage drives the registry market. The substantially lower Denver figure has occasionally drawn collector attention from set builders who follow Denver-Philadelphia mintage disparities across the series. Roll hunters in the south-central states still recover MS65 examples from original bank rolls.
