Jose I gold 6400 Reis 1766-R AU55 NGC, Rio de Janeiro mint, KM172.2. A lightly worn example with handsome patination and a few notable marks on and around the bust. As is typical for the type, some softness is noted on the reverse design elements, but even still, this is an attractive example well-deserving of attention.
Estimate: 1000-1200 USD
