The first specimen was lot 23273 in Heritage sale 3020 (Long Beach, September 2012), where it sold for $2,467.50. The catalog description[1] noted, "Pedro I 640 Reis 1825R, lightly toned XF, tiny ding in the obverse field near the 4 of the denomination. Rare variety with 18 stars surrounding the globe. From The Santana Collection of 640 Reis." This silver 640 réis was minted at the Rio mint 1824-27. These coins would have traded in the 18th century as two-thirds of a Spanish dollar. In 1768 the weight of this denomination was lowered from 19.32 grams to 17.80 grams. Earlier silver 640 réis are known, starting in 1695. Of this type, the 1824 and 1825 are reasonably available.

Recorded mintage: 353,000.

Specification: 17.92 g, .917 fine silver, .528 troy oz ASW.
