50 Avos

Portugal retained Macau as a colony well into the twentieth century, and the 1952 coinage reform introduced a decimalized series replacing the older pataca-based fractions that had circulated alongside Chinese cash coins for decades. The 50 Avos was among the first issues struck under the new arrangement, produced at the Casa da Moeda in Lisbon rather than locally — Macau had no mint of its own.

Surviving examples in circulation grades are frequently found with significant edge wear, a known consequence of the coin's relatively light weight interacting with the hard surfaces of Macanese market stalls and gambling tables.
