Description
The United States Mint has issued proof American Silver Eagles alongside the bullion program since 1986. Each proof contains exactly the same silver as the bullion coin, one troy ounce (31.103 grams) of 99.9% pure silver, and measures 40.60 mm across with a reeded edge and a $1 face value. The difference lies in how it is made and presented.
Proofs are struck more than once on specially polished dies. The result is frosted design elements set against mirror-like fields, revealing every detail of Adolph A. Weinman’s Walking Liberty on the obverse, with Liberty striding toward the rising sun, draped in the flag. Proofs dated 2021 and later carry Emily Damstra’s eagle landing with an oak branch on the reverse; earlier proofs show John Mercanti’s heraldic eagle. Depending on the year, proofs carry a W mintmark for West Point or an S for San Francisco.
Each coin is sold in a U.S. Mint presentation case with a certificate of authenticity. Keeping the coin, case and certificate together supports resale value.
Proofs are made for collectors, and their price reflects that craftsmanship and limited annual production, so the premium is substantially higher than for the bullion coin. Buyers focused on silver content per dollar are usually better served by the bullion version. Proof Silver Eagles are generally covered by the tax code’s exception for American Eagle coins, though custodian policies on proofs vary.
