Otherwise known as the "Pillar Dollar" or "Piece of Eight", this coin is the forerunner of the U. S. silver dollar. Before the Mint Act of 1792, the dollar value referenced in the Constitution is of the Spanish Milled Dollar. The coin remained legal tender until 1857 in the U. S. and circulated freely throughout the Americas. This piece was minted in Mexico City while Ferdinand VI ruled Spain.
