The 960 réis (“patacão”) is Brazil’s most famous silver coin: beginning in 1810, Spanish colonial 8-reales pieces (“Spanish dollars”) already circulating in Brazil were overstruck with Brazilian dies. Understrikes often peek through, making every coin a two-history piece. This entry explains the overstrike, what to look for, and why collectors pay premiums for clear host detail.
Key facts
- From 1810, Spanish 8-real coins were overstruck to produce 960-réis coins; in 1809 older Brazilian silver and copper had instead been counterstamped with the Portuguese arms and revalued.
- The host coins were the world-famous Spanish “pillar” and bust 8 reales — traces of the undertype frequently show through the Brazilian strike.
- 960 réis sat atop the silver hierarchy (alongside 80/160/320/640 réis issues) in the late colonial period.
- Because each coin is struck over a unique host, no two are exactly alike — undertype visibility, date readability, and original detail drive desirability (desirability is a market observation, not a value claim).
