Money, Moolah, Cash
In Brazil the sides of the coins are known as cara (face) and coroa (crown). They're equivalent to “heads” and “tails” in English.
In the late '90s the Real coins were given a revamp, and the new style/pictures were chosen by the general population in a contest made by Brazil's national bank (Banco Central do Brasil).
On the coroa side: Tiradentes, with the flag from his revolt in the background.
Tiradentes is considered to be a martyr for the independence of Brazil. He was a leader in a revolt to become independent from Portugal and when it failed he was publicly hanged.
The flag from his revolt is now the flag of the state of Minas Gerais.
His nickname, Tiradentes (Teeth Remover), is due to the fact that he was a dentist.
