Pedro I copper Pattern 6400 Reis 1830-R, KM-Pn36, Russo-E29a, MS62 Brown NGC. Chocolate light brown toning for this lovely and rare pattern of Pedro I. Interestingly, this issue suggests that 6400 Reis were to be produced in 1830 although there are no records of any Pedro I gold coins being struck after 1828. Extremely Rare.
