KM: "In order to prevent chaotic conditions resulting from local and private countermarking, the government passed Law#54 of 6 October 1835 ordering all coppers countermarked according to the following standards:
2 oitavos = 7.18 g = 10 Reis
4 Oitavos = 14.34 g = 20 Reis
8 Oitavos = 28,69 g = 40 Reis
The countermarks consist of neat numerals within a circle, having a plain or shaded field."
