Got that one as well, as far as the 5 centavos, its "unmil novecientos diecinueve" I believe mines 1919 so google translate says.
Peru 10 Centavos 1879 Peru 5 Pesetas 1880 I visited Peru in 1981 and 1982 and really enjoyed the trip.
1 sol 1981, brass, mintage - 51630000 pcs. The design of coin is primitive enough. It seems strange, as, for the Peruvian coins an elegant design is characteristic.
