History and Context

The 10 Cruzeiros coin from 1990 belongs to the period of the so-called “Collor Plan” / “New Cruzeiro,” when Brazil experienced high inflation and frequent monetary changes. The Cruzeiro (Cr$) was reintroduced on March 16, 1990, replacing the Cruzado Novo, and remained in circulation until later replaced by other monetary units.

This coin reflects a part of the Brazilian economy at the time, marked by instability and the need for monetary reforms.
