The American Silver Eagle is a popular one-ounce silver bullion coin produced by the United States Mint since 1986. The 2018 edition features an obverse design by Adolph A. Weinman showcasing the Walking Liberty and a reverse design by John Mercanti depicting the heraldic eagle. These coins are minted in .999 fine silver and are legal tender with a nominal value of one dollar, although their market value is significantly higher due to their silver content and collector demand.
