Bolivia 1718 real rev H3029-30363.jpg

This specimen was lot 30363 in Heritage sale 3029 (New York, January 2014), where it sold for $7,637.50. The catalog description[1] noted, "Felipe V Heart (Corazon) Shaped Real 1718 P-Y, VF30 NGC. Some double-striking is noted, with the normal piercing seen on virtually every genuine heart-shaped cob. The date is clear and the shape perfect for the type with perfectly aligned medallic axes, a nicely formed stem at the to[p], and a gently curved tail. The exact reason for the production of these pieces is unknown, but it is thought to have some religious significance, and the pieces were worn, in various ways, by women members of the Church." 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 This type was struck 1702-28 and was superseded by a later type (KM 28a) which was .917 fine silver. 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.

Specification: 3.38 g, .931 fine silver, .101 troy oz ASW.
