Are Gold Buffalo Coins Legal Tender?

By GovMint :

Gold Buffalo coins, also known as American Buffalo coins, are indeed legal tender in the United States. These one ounce coins were first minted in 2006 and carry a face value of $50, backed by the U.S. government. Despite their significant intrinsic gold content, Gold Buffalo coins hold the status of legal tender, meaning they can technically be used as a form of payment for goods and services at their nominal face value, however their collector appeal generally far exceeds their face value.
