Brazil 1790 80 reis
This specimen is a type struck at the Lisbon and Rio mints 1787-90 and 1796. It is the "high arch crown" variety, distinguished from the "low arch crown" variety (KM 219.1) by having the rear arch of the crown visible above the shield. Similar silver eighty réis were struck at Rio during 1810, 1814 and 1816 (KM 305) and at Bahia during 1821 (KM 322.2). All are scarce, especially compared to the later copper eighty réis, which was issued in large quantities starting in 1818. The copper eighty réis continued into the reign of Emperor Pedro I (1823-32) but the silver eighty réis is restricted to some very rare issues of 1824, 1826 and 1833 (KM 372 and KM 388).
Earlier silver eighty réis are known, starting in 1695 (see KM 77, 78, 87, 160, 167, 190 and 204). All are scarce to rare.
Recorded mintage: 92,000 (all varieties).
