This round-global design is on all kinds of old Brazil coins. What is this round-global design called? I assumed that it was the COA of Brazil's first empire. However, I don't find it called the COA on the Internet. I guess I'm asking how you would describe the obverse & reverse of this 1781 80 Reis coin?
The device on the reverse is an armillary sphere. I'd describe the coin as: Crowned coat-of-arms / Armillary sphere on cross potent
