Cobs and Macuquinas from Potosi, Bolivia coins

Silver Cobs of Potosi, 1574-1773

Bolivian silver cobs

Potosi, BoliviaWhen it comes to silver cobs, no mint was more prolific than Potosi, Bolivia, where an entire mountain of silver was discovered in the early 1500s. It took a little while before authorities figured out that a mint was needed on site, where the silver was being mined, even though the extreme remoteness and elevation presented major problems that were never fully resolved. The most egregious problem, perhaps, was an almost lawless environment where silver barons controlled the government and took full advantage by owning and profiting from mint offices and even by debasing the silver itself, causing a major scandal that put the entire world on its financial ear in the mid-1600s. Up to that point Potosi struck shield-type cobs, some of which were then recalled and either melted or countermarked (to attest to proper fineness) in 1652. To rectify the whole system, a new design was begun in that year, starting with some "transitional" issues and culminating in the pillars-and-waves design that became a global mainstay again throughout the rest of the 1600s and most of the 1700s. In 1773 the last cob ever struck came off the press in Potosi, long since superseded by milled coins (begun there in 1767).
