Escudo of D. Carlos I

The most intriguing fact about these coins is that, despite being associated with D. Carlos I's reign, they were denominated in réis, not escudos—the escudo system didn't arrive until after his death in 1908. This mix-up often confuses collectors, but it's a straightforward reflection of Portugal's halting monetary shifts.

Struck in silver at the Lisbon mint, these pieces typically featured the king's portrait on the obverse and the national arms on the reverse, with designs that varied little year to year. Mintage records for specific years are spotty; many were likely destroyed in the 1910 republican revolution. We know production ramped up in the 1890s to stabilize the economy, but exact numbers remain elusive.

Not every coin from this era survived intact—wear from circulation was common, given their use in daily trade. As for myths, I've heard tales of hidden treasures, but that's just idle talk; most ended up as pocket change. A silver 1000 réis from 1906 once fooled me into thinking it was rare, until I checked the catalogs.
