Bolivia 1753-P C real
This specimen was lot 1934 in Sedwick Treasure Auction 39 (Winter Park, FL, May 2026), where it sold for $144. The catalog description[1] noted, "BOLIVIA, Potosí, cob 1 real, 1753 C/q, rare. Rare over-assayer (clear) and a nice VF example at that with bold date between pillars, well-centered cross, naturally crude edges." The Potosí 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 This type was struck 1748-60 and superseded an earlier type (KM 28a) which names Philip V instead of Ferdinand VI.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 Potosí mint was the last to abandon the manufacture of cobs, in 1773. Assayer "C" operated 1753-54 and shared the duties with assayer "q" (1748-60).
