The 1 Cruzeiro coin from 1970 is one of the most representative pieces from Brazil’s period of monetary modernization during the military regime. Part of the currency system established after the 1967 reform, it belongs to a series of widely circulated metal coins used throughout the late 1960s and early 1970s.
Historical Context
In 1967, Brazil replaced the old Cruzeiro with the New Cruzeiro (NCr$), equivalent to one thousand previous cruzeiros. By 1970, the country was experiencing the so-called “economic miracle,” and the coins minted in this period reflect the government's attempt to standardize and modernize the economy.
The 1 Cruzeiro coin issued in 1970 marks the early phase when the “N” prefix (“New”) was removed, returning the currency to the name Cruzeiro.

Mintage and Circulation
The 1970 mintage was high, as this was a widely used denomination. Because of this, circulated examples are not considered rare. The most valued pieces are those in Uncirculated (UNC) or Choice Uncirculated condition, since most coins saw heavy daily use.
Current Numismatic Value
A coin’s value depends on three main factors:
- Condition (the most important)
- Collector demand
- Rarity (or relative lack thereof)
The 1970 1 Cruzeiro is common, but still sought by collectors completing type or year sets.
Average market values (2024–2025):
- Circulated (Good to Fine): R$ 1.00 to R$ 5.00
- Better preserved (VF to XF): R$ 5.00 to R$ 12.00
- Uncirculated (UNC): R$ 15.00 to R$ 30.00
- Special sets or proofs: Can exceed R$ 80.00, depending on preservation and origin
(Values may vary according to seller, region, demand, and catalog used.)
Curiosities
- The 1970 coin series is popular among new collectors because of its accessibility and representation of an important economic period in Brazil.
- Many pieces were preserved simply because they remained stored in drawers or family collections after losing monetary value due to later currency changes.
Conclusion
The 1970 1 Cruzeiro coin is not rare, but its historical importance and distinctive design make it an interesting addition for both beginner and experienced collectors. Its numismatic value may not be high, but it increases significantly when the piece is in excellent condition.
For those who appreciate Brazil’s economic history, it stands as a small symbol of a transformative era.
