The Three Dollar Gold Piece, also known as the "Three Dollar Coin," was minted by the United States from 1854 to 1889. The 1866 Three Dollar Gold Coin, produced in Philadelphia, is particularly notable as it marks the first year after the introduction of the design that included "In God We Trust," which would eventually become a standard for U.S. currency. This coin features a design by U.S. Mint engraver James B. Longacre, with the obverse depicting a Liberty head and the reverse showcasing a wreath. The Three Dollar Gold Coin is a rare collectible, often sought after by numismatists due to its unique denomination and historical significance.
