2017-D Ozark

Denver's 2017 Ozark output reached 201,600,000 pieces, running 27.6 million ahead of Philadelphia's 174,000,000 for the same design and reversing the closer-spread pattern that defined the other four 2017 ATB designs. The roughly 28-million Denver advantage on this date is the largest single-design P-versus-D gap of the 2017 year and reflects how Federal Reserve quarter ordering shifted unpredictably between the two mints even within a year of otherwise tighter spreads. Chris Costello's reverse, with the johnboat-and-cottonmouth composition along a Missouri Ozark bluff, was the first of two Costello-credited ATB designs (the second being 2019's San Antonio Missions).

Strike quality on the Denver issue often runs marginally crisper than Philadelphia in the canoe planking and the bluff's rock face shadowing, though die-state variation across the production run is the bigger factor in any specific example's grade. The composition follows the standard clad formula (75% copper-nickel outer layers bonded to a pure copper core, 5.67 grams total weight, 24.26 mm diameter), and authentication concerns are essentially nil for circulation-strike modern clad coinage. Counterfeiters do not target this issue. The high-grade market runs through PCGS and NGC, with raw MS65 to MS66 examples remaining findable in original bank-wrapped Denver rolls.

The 2017-D Ozark is a Regular-classification issue with one of the more distinctive reverse compositions in the year's group. The narrative scene (a boy in a canoe, a snake at the bank, a bluff overhead) gives the date a collector hook that pure landscape designs lack, which sustains slightly firmer demand at MS68 even though the raw mintage sits in the middle of the year's range. Registry set builders working toward the complete 56-design run absorb the limited top-grade supply, and listing prices for true MS68 examples have held steady year over year.
