Unraveling the Mystery: What Were the 9 Pieces of 8?
When you hear the phrase "pieces of eight," images of swashbuckling pirates, buried treasure, and doubloons likely come to mind. But what exactly were these famed pieces of eight, and why are they so ingrained in our historical and cultural consciousness? This article delves into the fascinating history and significance of this iconic currency.
The Genesis of the Piece of Eight: The Spanish Silver Dollar
The "9 pieces of 8" refer to the Spanish silver dollar, also known as the Spanish milled dollar or the peso de ocho. This coin was the most widely circulated currency in the Americas and Asia for centuries, beginning in the late 15th century and continuing through the 19th century.
Why "Piece of Eight"?
The name "piece of eight" comes from the coin's ability to be physically divided into eight smaller pieces, or "bits." This practice was common when larger denominations were inconvenient for everyday transactions. Each of these eight pieces was worth one real, a smaller Spanish silver coin. Therefore, the entire Spanish dollar was equal to eight reales, hence "piece of eight."
The Journey and Impact of the Spanish Silver Dollar
The Spanish Empire, through its vast colonial ventures in the Americas, especially in Mexico and Peru, produced an enormous quantity of silver. This silver was minted into these highly recognizable coins.
- The Potosí Mint: The Spanish mint in Potosí, Bolivia (then part of Viceroyalty of Peru), was one of the most prolific in the world, churning out millions of these silver dollars.
- The Mexico City Mint: Similarly, the mint in Mexico City was a major producer of these coins.
- Global Circulation: The Spanish silver dollar's high silver content, consistent weight, and uniform design made it a trusted medium of exchange across vast distances. It was the de facto international currency for trade between Europe, the Americas, and Asia, particularly in the bustling trade routes with China.
The "Cob" and the "Milled" Dollar
It's important to distinguish between two types of Spanish dollars:
- Cob Coins: These were irregularly shaped coins made by striking metal by hand. They were crude but functional.
- Milled Dollars: Later, Spain adopted more sophisticated minting techniques using machinery. This resulted in the more uniform, round, and intricately designed "milled" dollars, which were the true "pieces of eight" most commonly associated with the legend. These coins often featured the profile of the Spanish monarch on one side and the royal coat of arms on the other.
The Piece of Eight in Popular Culture and History
The enduring image of the "piece of eight" is deeply intertwined with the Golden Age of Piracy. Pirates, both real and fictional, are often depicted hoarding these coins.
"The Spanish silver dollar, or piece of eight, was the currency of pirates and privateers. Its widespread acceptance and the ease with which it could be broken down into smaller denominations made it a practical choice for those operating outside the established legal framework."
The United States dollar itself was, for a time, pegged to the value of the Spanish silver dollar. Early American coins were often patterned after or directly represented pieces of eight.
How to Identify a "Piece of Eight"
Genuine Spanish milled dollars, the true "pieces of eight," are typically made of 90.28% silver and weigh around 27 grams. They often bear the Spanish royal crest or Pillars of Hercules on the reverse, and the monarch's profile on the obverse.
