Portugal 1790 400 reis
This specimen was lot 25308 in Heritage sale 3019 (Chicago, April 2012), where it did not sell. The catalog description noted, "Maria I gold 400 Reis 1790, AU50 NGC, sharply struck details, very attractive for this diminutive gold type." This denomination, called a "cruzado novo," was struck intermittently throughout the eighteenth century. This type is recorded for 1787, 1790, 1795 and 1796 of which the 1790 is the most common. At some point the coin was revalued to 480 réis but continued to be struck bearing "400" on the obverse.
