Watch List notes:

Tierra del Fuego (struck in Buenos Aires), Argentina, gold 5 gramos, Popper, 1889, rare, NGC MS 63. Janson-5; KM-Tn8. Choice luster with light purplish toning, very natural-looking and pretty, the rarer of just two denominations in a one-year type (highly sought by numismatists) struck by Romanian-Jewish gold-prospector Julius Popper using gold dust found on the beach of El Paramo in the Patagonian peninsula. Popper's expedition, under the name of Gold-Washing Company of the South (Lavaderos de Oro del Sud), achieved a sort of autonomy, with its own army and coins and stamps, as well as a notorious "wild west" atmosphere replete with crime and abuse of natives. Popper died suddenly and mysteriously in 1893.

Estimate: $6000 - $9000
