Coins in Macau (aka Macao) use the pataca; 1 pataca = 100 avos. The first Macanese coins were issued in 1952, during the Portuguese colony era.
Macau’s coins were originally round, but some changed to 12-sided in the 1990s.
Proof coins and special edition coins are often available for Macau coin collectors, and include some striking designs, often featuring animals.
