Its buyback value rests on the fine weight times the day's spot price, plus a premium driven by demand. ## The official silver coin of the United States The American Silver Eagle is the US Treasury's silver investment coin, issued since 1986. It weighs **one troy ounce (31.1035 g)** with a fineness of 999, about 31.07 g of fine silver. Its obverse features the "Walking Liberty" design and its reverse a heraldic eagle, redesigned in 2021. It is a widely recognised and liquid **bullion** coin. There are also "Proof" and "Burnished" versions aimed at collectors, which may carry a higher premium. For everyday buyback, it is mainly the bullion version, bought for its metal, that circulates on the recycling market. ## Estimating its buyback value The metal value is calculated as: **31.1035 g × 0.999 × the day's silver price**. The world spot is the same for everyone; what sets two offers apart is the professional's margin and the coin premium. The American Eagle, being popular, often shows a slightly higher premium than other ounces at purchase. To judge a buyback offer, compare it with the fine weight times the current spot. Our [silver buyback](https://meilleur-rachat-argent.fr/en/silver-buyback/) page lets you weigh up several professionals. The calculation logic is the same as for the [Silver Maple Leaf](https://meilleur-rachat-argent.fr/en/guides/silver-maple-leaf-value/): only the premium gap varies. ## Premium, versions and buyback The American Eagle's **premium** depends on the version (bullion, Proof, Burnished), the year, condition and current demand. Proof versions, sold in cases, are more of a collector item and may retain a numismatic premium; bullion coins trade close to the metal. At buyback, the professional authenticates the coin (weight, dimensions), identifies the version and year, then applies its schedule. Payment is made by bank transfer or cheque above cash limits, with ID and register entry. A coin in its original capsule, uncleaned, is generally better valued than a handled coin. ## Frequently asked questions What is the fineness of the Silver American Eagle?
