Check the date, Paula. You likely have a 1922 coin. That was the year of Brazil's 100th birthday. Both the 500 reis and 1000 reis coins were minted with the same pattern in aluminum bronze. The 2000 reis that year looks the same on the front, but it has a different reverse and it is made of silver. The small picture shows the back of the 2000 reis coin.
