Historical Significance
Oregon was the 33rd coin issued in the 50 State Quarters Program and represents Oregon as the 33rd state admitted to the Union. The design centers on Crater Lake, one of the state’s most famous natural landmarks and the deepest lake in the United States, making this quarter especially appealing to collectors who enjoy nature-themed U.S. coin designs.
Collectibility
The 2005-S Oregon clad proof is a strong option for collectors assembling complete State Quarter proof sets, modern U.S. proof quarter runs, or Oregon-themed collections. Its mirrored proof finish, dramatic Crater Lake reverse, and companion silver proof counterpart give it solid appeal within the long-running series.
