Sincona sale 9, lot 3606
This specimen was lot 3606 in Sincona sale 9 (Zurich, October 2012), where it sold for 1500 CHF (about US$1,897 including buyer's fees). The catalog description[1] noted,
"BRASILIEN Pedro II. 1831-1889. 10000 Reis 1842, Rio. Hksp. Sehr schön-gutes sehr schön. (Brazil, Peter II, 1831-89, ten thousand réis of 1842, Rio mint, mount removed, very fine to good very fine.)"
This type was struck 1841-48 and tho denominated 10,000 réis, was the same size and weight as the colonial 6400 réis. In 1849, the 10000 réis was lowered to 8.96 g, where it remained until 1922. It is likely that the 1840's issues were melted down to strike the lighter coins as this type is now very rare.

Recorded mintage: 1,146.

Specification: 14.34 g, .917 fine gold, .423 troy oz AGW; this specimen 14,33 g.

Catalog reference: Russo 659. Fr. 118, KM 457.
