The money in Brazil is the Real, and is
indicated by R$. The exchange rate right now is about 1.8 = $1US
so not quite double. Here's how it looks:
The coins from the top are 1 Real, 50 centavos, 10 centavos (1997), 5
centavos, and the copper one is 10 centavos (2005). On the front
is what looks to me like a Greek or Roman statue and the name says
"Deus Seja Louvado". On the back
of the currency are various local animals. The 10 has the Arara, the 20
the Mico-Lead-Dourado and the 50 the Onca-Pintada. The bills are all
the same size, though different colors.
8/13: I took some other pictures of the currency, also I acquired a 5
Reais and two 25 centavos, from 1995 (silver) and 2004 (copper). The
coins are not the same size.
The 5 Reais has the Garca on the back.
