Historical Significance
Minnesota was the second State Quarter released in 2005 and the 32nd coin issued in the 50 State Quarters Program, matching Minnesota’s place as the 32nd state admitted to the Union. The design emphasizes the state’s outdoor identity and lake culture, making it one of the more regionally distinctive quarters of the series.
Collectibility
The 2005-S Minnesota clad proof is a strong option for collectors building complete State Quarter proof sets, modern U.S. proof quarter runs, or Minnesota-themed collections. Its mirrored proof finish, widely admired lake-and-loon reverse, and companion silver proof issue give it solid appeal within the long-running series.
