wow!!! sweet coin. I am having fun looking your coins up in my 18th century Krause catalog. KM#172.2 Brazil, 6400 Reis, 1753-B, mintage- 475,000 .917 gold
Thanks, I almost won a 1727-M 20,000 Reis Joao V last Numisma auction. These big guys are affordable, most coins that weight/size are not. Checkout the lastest Rauch auction(April) under Holy Roman/Habsburg coins, a lot of beauties!
