Spanish Colonial Coinage: A Comprehensive Guide to the Coins and Currency Circulating in Spanish America, from the Conquest to Independence

The Early Days: From Conquest to the First Mints

The Spanish conquest of the Americas in the early 16th century led to the need for a stable currency system. Initially, the Spanish used cobs, irregularly-shaped silver coins that were crudely cut and hammered, as the primary form of currency. These cobs were produced in Spain and shipped to the colonies, where they became the foundation of the colonial monetary system.

The First Mints in Spanish America

As the Spanish Empire expanded, the need for local mints became apparent. The first mints were established in Mexico City (1535) and Lima, Peru (1568). These mints produced the famous Pillar Dollar, also known as the Spanish Dollar or Peso de Ocho, which became the most widely circulated coin in the Americas and played a crucial role in international trade for centuries.

Types of Spanish Colonial Coins

Spanish colonial coins can be broadly divided into several categories, each with its own unique characteristics and history.

  1. Cobs: Crudely struck, irregularly shaped coins produced in Spain and the early mints in the Americas.
  2. Pillar Dollars: Also known as Spanish Dollars or Pieces of Eight, these were widely circulated and highly regarded coins.
  3. Portrait Series: A series of coins featuring the portraits of Spanish monarchs, introduced in the 18th century.
  4. Provincial Coinage: Locally-produced coins that circulated in specific regions of Spanish America, often made from copper or bronze.


Cobs, also known as macuquinas, were the first coins produced for use in Spanish America. Produced in both silver and gold, these coins were valued based on their weight and fineness rather than a fixed denomination. The irregular shape and crude production techniques resulted in a wide variety of sizes and designs, making them highly sought after by collectors today.

Pillar Dollars

The Pillar Dollar, introduced in the mid-16th century, was a major improvement over the cob coinage. These coins featured a design with two columns (or pillars) representing the Pillars of Hercules, which symbolized Spain’s claim to the New World. Pillar Dollars were produced in various denominations, including the famous 8 Reales, and became the standard currency for international trade in the 17th and 18th centuries.

Portrait Series

Introduced in the 18th century, the Portrait Series featured the busts of Spanish monarchs, starting with King Ferdinand VI. These coins were more uniformly produced and had a consistent design, making them easily recognizable. The most famous Portrait Series coin is the 8 Reales featuring King Charles III, which continued to be minted until the early 19th century. The Portrait Series coins were produced in various denominations, from ½ Real to 8 Reales for silver and 1 Escudo to 8 Escudos for gold.

Provincial Coinage

Provincial coinage refers to the coins that were minted and circulated within specific regions of Spanish America. These coins were often made from copper or bronze and featured local designs and denominations, making them an interesting study for collectors. Examples of provincial coinage include the copper maravedis of Santo Domingo and the bronze coppers of Popayan, Colombia.

Key Mints and Their Significance

Throughout the Spanish colonial period, numerous mints were established across Spanish America. Some of the most important and well-known mints include:

  • Mexico City: The first mint in the Americas, established in 1535. It produced a wide variety of coins, including cobs, Pillar Dollars, and Portrait Series coins.
  • Lima: Established in 1568, the Lima mint produced coins similar to those from Mexico City, as well as some unique denominations and designs.
  • Potosí: Founded in 1574 in present-day Bolivia, the Potosí mint was responsible for producing a significant portion of the Spanish Empire’s silver coinage due to the vast silver deposits in the region.
  • Bogotá: Established in 1622, the Bogotá mint produced gold and silver coins, with many of its coins featuring a distinctive design of a crowned shield.
