2006-D North Dakota

Denver's 2006 North Dakota quarter carries Donna Weaver's bison-and-badlands reverse: two American bison grazing in the foreground against the ridge-layered backdrop of Theodore Roosevelt National Park, the park named for the president whose Dakota-territory ranching years shaped his conservation politics. North Dakota's August 28, 2006 release positioned the Peace Garden State as the fourth 2006 issue. Denver produced 359,000,000 pieces, the highest single-mint output of the 2006 calendar year and a meaningful step up from Philadelphia's 305.8 million on the same design. Weaver's two-tier composition (foreground bison pair, middle-ground badlands) gives the design strong vertical readability and works as the natural framing for Denver's typical strike characteristics on long press runs.

Strikes on Denver North Dakotas come up cleanly defined more often than not, with the bison's hump and beard texture and the badlands ridge silhouettes serving as the natural detail registers. Weak strikes show up first as softness along the bison's mid-body and along the lower butte edges, where the relief sits deepest. Washington's cheek and hair-above-ear remain the obverse weak points for grading, and 2006-D bag handling typically caps many candidates at MS66. PCGS and NGC populations run deep at MS66, narrower at MS67, and meaningfully scarce at MS68 in the population reports kept by the two major third-party grading services (TPGs). No FS-listed varieties anchor to the issue.

The 2006-D North Dakota is the year's highest single-mint output and reads as the readily available standard for the bison-and-badlands design. The 359 million figure puts statistical pressure on premium strike availability: even at low percentage rates, a population that large produces meaningful absolute counts of MS66 and MS67 candidates in third-party grading service population reports. Roll searchers continue to pull premium strikes for full-detail gems, and MS67 examples remain available for collectors completing a top-grade run on a working budget. The design pairs naturally with the South Dakota Rushmore reverse in Dakotas-pair subsets. For wider context, see the 50 State Quarters series history.
