This silver piece of eight or Spanish colonial real, made in Mexico in 1807, was the precursor to the US Silver Dollar. King Charles of Spain's profile in soldier's dress with laurel wreath shows on the front of coin with "CAROLUS IIII DEI GRATIA 1807" inscribed around the edge. "HISPAN ET IND REX M 8R T H" and crowned Spanish arms between the Pillars of Hercules show on the reverse. The "chop marks" on the edges of the coin reveal that it was circulated in China. The marks were punched into the coins to test the silver content. An article in the August 28, 2017 issue of Coin World noted that a 1775 accounting of George and Martha Washington's coins and paper money listed "silver dollars, 500@6/", or Spanish colonial 8-real coins at 6 Virginia shillings each, plus five English half crowns and 14 "doubloons." A copy for the article is included with your purchase. Silver pieces of eight were legal tender in the U.S. until 1857. Coin is approximately 1 ½" in diameter. This is an original coin, not a reproduction.
