Historical Significance
North Dakota was the 39th coin released in the 50 State Quarters Program and commemorates North Dakota as the 39th state admitted to the Union. Its design emphasizes the state’s Badlands region and bison heritage, giving the coin broad appeal with both State Quarter collectors and collectors of western Americana themes.
Collectibility
The 2006-S North Dakota clad proof is a solid choice for collectors building complete State Quarter proof sets, modern U.S. proof quarter runs, or North Dakota-themed collections. Its mirrored proof finish, popular bison design, and San Francisco proof format make it a dependable modern issue, while the separate silver proof version offers a scarcer companion piece for set builders.
