The 1878 Trade Dollar is a collectible coin produced by the United States Mint, primarily intended for trade with Asia, particularly China. The coin features a seated Liberty design on the obverse and an eagle on the reverse. Although it was authorized by the Coinage Act of 1873, the Trade Dollar was largely discontinued for circulation domestically, leading to its status as a collectible item. Its historical significance and limited mintage contribute to its appeal among coin collectors.
