This silver 640 réis was minted at the Rio mint 1809-16. 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. Many are priced very low in the SCWC but the 1812-R thru 1816-R are rare. The specimen was lot 20477 in Heritage sale 3009 (Chicago, April 2010), where it sold for $546.25. The catalog description[1] noted, "João Prince Regent 640 Reis 1814R, nice XF, lightly toned with bold details. Struck over an earlier coin." The SCWC lists 1809-R and 1811-R as common for the type, which was also produced at Bahia (KM 256.1).
