Before the Morgan dollar or even the Pine Tree Shilling, metal coinage circulated in the American colonies. Much of it arrived with settlers from their home countries, but one coin stands out as a product of the Americas. This coin existed only because of the immense wealth discovered in the New World: the Spanish Piece of Eight.
What Is a Piece of Eight?
The Spanish piece of eight, also known as the 8 Reales or Spanish milled dollar, originated in 1497. It quickly became the most influential silver coin of its time. Valued at eight reales, the standard Spanish monetary unit, the piece of eight became widely accepted across Europe, the Americas, and Asia.
These coins played a key role in global trade for centuries, becoming the backbone of the Spanish economy and, by extension, many colonial economies, including the early American colonies. Thanks to its silver content and international trust, the piece of eight eventually inspired the design of the U.S. silver dollar.
The Rise of Spanish Colonial Power and Coinage
If you know your American history, you’ll know that the English were not the first to explore North America. They were simply the ones who settled most of what is now the United States and Canada. Many countries in Europe were interested in finding and claiming new territories. These include France, the Netherlands, Portugal, and, of course, Spain.
From Columbus’s historic voyage in 1492 well into the 18th century, Spain conquered territory after territory until it became the largest empire in the world. It was “the empire on which the sun never sets” long before Great Britain was. As Spain became the world’s most powerful empire, it needed a reliable, valuable, and transportable form of currency to fund its operations.
In the mid-16th century, the Spanish discovered a rich vein of silver in Bolivia’s Potosi, the “mountain of unimaginable riches.” To mine it they enslaved both indigenous Bolivians and slaves from Africa. Eventually 40,000 tons of silver were shipped from this site alone, and a mint opened to coin pieces of eight.
A tremendous amount of currency was generated and went all over the Spanish empire, funding wars, conquest, and settlement projects. Because they were made of silver, these coins had inherent value and were used for trade even outside the empire, including in the American colonies, in Asia and throughout the world.
A small fraction of these coins made their way into the hands of pirates. Most of them got to their intended destination, however, because Spanish kings tended to frown upon entire shiploads of silver and gold going missing and took precautions. Spanish authorities heavily guarded their silver shipments with armed galleons and convoy systems to prevent theft.
Pirates, Literature, and Pop Culture Fame
What made the piece of eight legendary wasn’t just its historical significance, but its presence in popular culture. Robert Louis Stevenson’s Treasure Island popularized the coin in pirate lore, and it later appeared in films like Pirates of the Caribbean. These stories immortalized the piece of eight as the ultimate symbol of hidden treasure.
Features of the Spanish 8 Reales Coin
Pieces of eight were large, heavy silver coins. Early designs featured the pillars of Hercules and the Spanish coat of arms, while later designs incorporated the portrait of the reigning Spanish monarch. The coins minted in the Americas are particularly valuable to collectors.
- Silver Content: High-purity silver, giving the coins intrinsic value
- Size: Large and heavy, often around 38-40 mm in diameter
- Designs: Varied across time and mints, including pillar dollars and portrait coins
- Cultural Legacy: The phrase “two bits,” still used in American English today, refers to a quarter of a piece of eight (i.e., two reales)
Historical and Numismatic Value Today
The Spanish piece of eight remains highly sought after by coin collectors and history enthusiasts alike. These coins are relics of early global trade, European colonization, and monetary evolution. Their connection to the founding of the U.S. monetary system makes them especially significant in American numismatics.
Whether you’re interested in historical coin collecting, pirate-era artifacts, or early silver dollars, the Spanish 8 Reales coin is a fascinating piece of numismatic history.
