Maria I gold 6400 Reis 1798-R AU58 NGC, Rio de Janeiro mint, KM226.1, LMB-O536. This piece feature some interesting waviness to the surface of the obverse; this does not reflect damage or alteration in any way, and merely indicates that an uneven planchet was used for striking. Otherwise appealing with a strong strike.
