Brazil 1818-R 960 reis KM 307
This silver 960 réis type was minted at the Rio mint 1810-18. These coins were usually struck over Spanish-American dollars but many other undertypes are known. Large quantities were produced, making this and the similar Bahia issue the commonest Brazilian silver coin of the colonial period.
This specimen was poorly overstruck, to the point where the overstriking image is not fully detailed. The undertype is a Mexico City eight reales. This was the last year the Rio mint struck this obverse design, switching mid-year to the United Kingdom type.
Recorded mintage: unknown.
