A Legacy of Empire and Silver
During the colonial period, the 8 Reales coin — commonly called a “Piece of Eight” — was the most widely circulated silver coin in the world. Accepted on nearly every continent, it was the de facto international currency before the rise of modern national systems.
This global dominance was made possible by the massive silver mines of Potosí in present-day Bolivia. The mint there produced millions of 8 Reales coins, feeding the Spanish empire’s economy and helping to fund European wars, colonization, and infrastructure. The “PTS” mintmark signifies this origin, while the “PJ” assayer initials connect it to the mint officials who guaranteed its weight and purity.
Coins like this served not only as economic instruments but as propaganda tools — spreading the image and authority of Spanish monarchs like Ferdinand VII across the New World and beyond.

Design Symbolism
The obverse features the bust of King Ferdinand VII, flanked by a legend that affirms his authority as King of Spain and the Indies. This side served as a political statement, reinforcing Spanish dominance in a region already stirring with rebellion.
The reverse features the Pillars of Hercules — ancient symbols for the Straits of Gibraltar — wrapped in a banner reading “PLUS ULTRA” (More Beyond). Between them sits the crowned arms of Spain, symbolizing control across the Atlantic and over the vast New World colonies.
The combination of regal portraiture and imperial symbolism served both aesthetic and strategic purposes — a blend of numismatic art and colonial influence.
Global Circulation and Influence
The 8 Reales coin circulated globally in the 17th through 19th centuries. It was accepted as legal tender in the United States until the mid-1800s, served as the template for the U.S. dollar, and was readily accepted in Asia, where it became central to trade networks in China and the Philippines.
This global utility made the 8 Reales a symbol of monetary trust, and coins from Potosí were particularly prized due to the region’s rich silver deposits and consistent standards.
Potosí: The Richest Hill in the World
The city of Potosí was built on silver. The nearby Cerro Rico (“Rich Mountain”) produced such vast quantities of silver that it funded the Spanish empire for centuries. Workers, including many indigenous laborers under brutal conditions, toiled in the mountain’s mines to feed the imperial mint.
The Potosí Mint itself became a center of precision minting and state power. Coins stamped with “PTS” left the city in vast quantities, but few remain in collectible grades today, especially those struck near the end of colonial rule — like this 1818 issue.
1818: On the Brink of Independence
This coin was struck just a few years before Bolivia’s independence in 1825. The region was in the midst of revolutionary upheaval, and Spanish authority was collapsing across Latin America. Yet this 1818 8 Reales still bears the likeness of King Ferdinand VII — a last attempt to assert control as power shifted to the people.
Coins from this era offer an extraordinary lens into history. They tell stories of empire, resistance, reform, and change — not just through imagery, but through timing. The 1818 date makes this a transitional artifact between two worlds: colonial empire and emerging republic.
