Description:
This 2006-S Colorado State Quarter, graded PF70 Ultra Cameo by NGC, is a perfect example of the highest quality proof coin. The obverse features the classic portrait of George Washington by John Flanagan, with inscriptions including "UNITED STATES OF AMERICA," "LIBERTY," "IN GOD WE TRUST," and "QUARTER DOLLAR." The reverse highlights Colorado's rugged Rocky Mountains, with the state nickname "Colorful Colorado" and the year of statehood, 1876, inscribed above. The Ultra Cameo designation emphasizes the striking contrast between the frosted design elements and the deeply mirrored fields, making this coin highly prized among collectors.
