The term Indian War Medallion is most commonly associated with circular, or oval, silver medallions distributed to Native American tribal representatives by representatives of the United States government. They were made in three sizes: small, medium and large. The largest could have a diameter of inches. The most common feature of Indian Peace Medals was the portrait of the current U.S. president. They are often cited as a symbol of the relationships between the United States federal government and Native Americans in the late-18th and 19th centuries. Indian Peace Medals were minted until the term of President Benjamin Harrison ended in 1893.
