The two gold coins issued privately in 1889 by Iuliu Popper, a Romanian-Jewish gold prospector, and his company "Lavaderos de Oro del Sud" in Argentinian part of the Isla Grande in Tierra del Fuego. The coins were minted in Buenos Aires from the alloy containing 86.4% Au, 13.2% Ag and 0.4% Cu. The value of the coins was given by their weight, hence the inscriptions on the coins: un gramo (1 gram) and 5 gramos. Gold sand and the prospector's tools are depicted in the centres of the coins.
