One argentino.

Argentino is a name given to two gold coins issued by Argentina from 1881 to 1896. The coins each had different values: 1 and ½ argentinos. One argentino was equal to 5 Argentine pesos oro sellado. Today, these coins are extremely rare, especially the ½ argentino, as only 421 were produced.
