The U.S. Merchant Token issued by Saml. Hart in 1978 is a rare and valuable piece of exonumia. This two-sided card token is composed of white metal and is in uncirculated condition, making it a desirable addition to any coin or token collection. Its origin from the United States adds to its historical significance, and its unique design and rarity make it a sought-after item for numismatists and collectors alike.
