Bolivia 1758 real rev DSLR.jpg

The specimen shown is a 1758 cob one real from the Potosi mint in Bolivia. The Potosi mint was the most prolific issuer of silver during the seventeenth and early eighteenth centuries, nearly all of it cobs such as this. This type was struck 1748-60 and superseded an earlier type (KM 28a) which names Philip V instead of Ferdinand VI. The other Latin American mints placed the date near the edge where it rarely struck up, whereas Potosi issues have the date smack in the middle, ensuring that the date would be legible even if the rest of the design was smeared. As a result, Bolivian cobs can be collected by date, unlike the other mints (Mexico, Lima, Guatemala). The Potosi mint was the last to abandon the manufacture of cobs, in 1773.

Recorded mintage: unknown.
