Carlos III Pillar 8 Reales 1770NR-VJ, KM39 (Date Unlisted), Calico 1000, Cayon Unlisted, MS64 NGC. Few world crowns demand so much numismatic interest as the Columnarios or Pillar Dollars that were struck from 1732 to 1773 in numerous Spanish mint houses throughout the Americas. By the second half of the 18th century, the Pillar Dollar had become a true "world currency" being widely used in Europe, the United States (where it was legal tender), and the Far East. Both old and new worlds are depicted on the coin's obverse and are crowned between the two pillars of Hercules with legends "VTRAQUE VNUM" (both are one). On the reverse, the arms of Castille and Leon are displayed under the Spanish crown with the denomination "8" to the right, assayer initials to the left.
