BRAZIL. 6400 Reis, 1778-R. Rio de Janeiro Mint. Maria I & Pedro III. PCGS AU-58. Fr-76; KM-199.2. Outside of some very subtle handling and a few darker flecks near the legends on the obverse, this wholesome survivor stands as a virtual Mint State specimen. Quite brilliant and appealing throughout. <strong>To view all items from the Mark and Lottie Salton Collection, click <a href="https://auctions.stacksbowers.com/lots?sort=auction_date_lot_number_asc&search=Salton+Collection&limit=36&lots_range=upcoming"> here.</a></strong> From the Mark and Lottie Salton Collection.
