HISTORY: The Mint at Potosi was the largest producer of silver coinage under the Spanish crown. Located in the High Andes of present-day Bolivia, The Potosi Mint was historically located in the Viceroyalty of Peru. The "P" Mint Mark stands for "Peru" and was used by this mint from its opening in 1575 until it's closing in 1825, long after the mechanical Screw Press replaced the centuries-old technique of hand-struck "cob" style coinage. The mines of Potosi are the richest in the world and produced most of the world (and Spain's) silver. Spain continued to exploit the mine's riches for four hundred years, making the country a central world bank. The city's Coat of Arms reads:
"I am rich Potosí, treasure of the world, king of all mountains and envy of kings.”
