2006 marks the inaugural year of the American Eagle Silver Uncirculated Coin Program. Struck on specially burnished blanks, this coin offers silver precious metal purchasers a new collectible version of the popular American Eagle Silver Bullion Coin and features a finish similar to its bullion coin counterpart. Each coin also bears the W mint mark reflecting its striking at the United States Mint at West Point. The artisans of the United States Mint have captured the grace and elegance of sculptor/engraver Adolph A. Weinman's celebrated Walking Liberty design.
The obverse design features an ever hopeful Liberty striding confidently toward the sunrise, draped in the strength of the Stars and Stripes carrying in her arms branches of laurel and oak to symbolize both civil and military glory.
The reverse design, by United States Mint sculptor John Mercanti, features a striking heraldic eagle with shield, and olive branch in the right talon and arrows in the left. The 2006 American Eagle Silver Uncirculated One Ounce Coin is encapsulated in plastic, inserted into a pouch, placed in a protective outer box, and accompanied with a custom-designed Certificate of Authenticity.
