2014-D Great Sand Dunes

Denver's 2014 Great Sand Dunes production reached 142,600,000 pieces, slightly below Philadelphia's 153,600,000 for the same design and one of the two 2014 issues where Denver came in below its Philadelphia counterpart. The narrow spread between mints, roughly 11 million pieces, is small enough that neither mint commands a meaningful premium today, though set builders sometimes note that 2014 was the year Denver's normal production lead briefly faltered across two of the five designs. Don Everhart's reverse, the hiker-and-child composition running across the dune field with the Sangre de Cristo Mountains rising behind, is the same design used at Philadelphia, struck from the same master dies.

Strike quality on the Denver issue tracks the broader 2014 Denver output: well struck on the kinetic foreground figures through the early die states, with predictable softening on the running silhouettes and the layered dune contours as dies aged. Graders concentrate on the figure outlines and the mountain ridgeline 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 findable 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 Philadelphia counterpart in slabbed grades. The kinetic figural composition has helped support steady collector interest in the Great Sand Dunes design across both mints, which has kept high-grade premiums slightly above what the headline mintage figures would suggest. Roll hunters in the central and Rocky Mountain states still recover MS65 examples from original bank rolls, though yield has thinned since the design's release year.
