1922 Brazil 200 Réis

The 1922 200 Réis coin was struck to mark Brazil's centennial of independence, a rare instance where a government issued a coin explicitly tying its design to a national milestone.

This silver piece, weighing about 2.5 grams and measuring 18 millimeters, features the Brazilian coat of arms on one side and the year 1922 prominently on the other. Mintage figures are murky; records from that era often went missing in bureaucratic shuffles.

While some claim it was hoarded for its silver content during the Depression, that's unverified. What we know is that it circulated briefly before fading into obscurity.

Plenty of collectors chase it thinking it's ultra-rare, but most turns up in decent condition. As for myths, let's just say I've seen enough to fill a drawer.
