More about the coin and its iconic design

The “pillar” series was first issued under Spanish Colonial rule at the Mexico City mint in 1732 and production lasted until 1772. This type was such an important source of coinage for the entire world economy that it was eventually struck at mints throughout the New World, harnessing the vast discoveries of silver. Production and mintage figures varied, producing some major rarities, especially in MS grade. For example, Peru only produced this type from 1751 until 1772. Remarkably, NGC has only graded 422 coins for the entire series of Peruvian Pillars, and the two dates offered here have impressive census figures.

It was designed to replace the hand struck “cob” series and featured cutting edge coin-press technology and perfectly circular planchets with a newly incorporated edge design. The latter novel characteristic was to prevent clipping, an all-important feature of the time since the coin’s exchange monetary value was directly linked to its intrinsic one. The precise silver content of this new design, coupled with its beautiful and striking design, helped cement and establish its place as the most important world trade coinage in the 18th and 19th centuries.

The obverse features two globes representing the “old” and “new” worlds atop the Atlantic Ocean encircled by the great “Pillars of Hercules” with the inscription PLUS ULTRA on the left and right ribbons on the columns, which translates to “MORE BEYOND”. The circular inscription “UTRAQUE UNUM” translates as “United we are one”.

The reverse shows the Castille and Leon coat of arms of the Spanish kings and the inscription “PHILIP V D G HISPAN ET IND REX” for “Philip V, king of Spain and the Indies by the grace of God”. The first part of the legend would change, reflecting the ruling Spanish King at the time.


The Pillars of Hercules were of course the well-recognized symbol for the Strait of Gibraltar separating the Atlantic Ocean and the Mediterranean Sea, and in Greek mythology represented the limits to the known world, a barrier not to cross. The ribbon atop the columns and the abbreviation “Ps” (for “Pesos”, the Spanish equivalent to an 8 Reales coin) are generally recognized as the origin for the current U.S. Dollar sign “$”.

Thus, the design on this coin symbolized the powerful united Spanish Colonial empire in Europe and the Americas that had expanded the boundaries of the known western world after Columbus’s 1492 voyage.

The Spanish Colonial “Pillar” Dollar issue quickly established itself as the most important trade coinage of the era in both the American and Asian commercial arenas and was legal tender in the United States until the Coinage Act of 1857. As such, it is rightly featured as one of the first coins listed in the current Red Book and noted as the most familiar currency in Colonial America.

The Pillars of Hercules Legend has it that Hercules smashed through a mountain, connecting the Atlantic and the Mediterranean Sea just south of Spain.
