History: The National Mint of Bolivia (Spanish: Casa de la Moneda de Bolivia) or the Mint of Potosí (in colonial era) is a mint located in the city of Potosí in Bolivia. It is from this mint that most of the silver shipped through the Spanish Main came. The coinage minted during its period became so well known in the world that a saying, memorialized by Miguel de Cervantes, came into use: valer un potosí, "to be worth a potosí" (that is, "a fortune"). Minting began immediately based on a rudimentary technology that remained for the next 212 years, from 1572 to 1767. As an Assayer, Tapia was known for the use of broken dies and transposition of the Lions and Castles on his coins.
