History & Notable Facts
The Macao 10 Avos was minted in Lisbon, a full hemisphere away from its intended use in a humid Asian outpost, underscoring the inefficiencies of colonial coinage logistics.
These copper coins, struck between 1920 and 1940, featured the Portuguese coat of arms on one side and a simple value inscription on the other. They weighed around 4 grams and measured 21 millimeters across, typical for the era's bronze issues. While exact designs varied slightly by year, most shared a plain edge and unadorned reverse.
Production details remain murky; mintage figures for specific years were likely lost in Portuguese archives over time. Some specimens show wear from tropical circulation, a testament to Macao's bustling port life.
I've seen plenty of these passed off as rarities, but they're common enough in circulated grades. As for that hole in some similar coins? This one doesn't have it, so don't ask.
