La Rioja 1840-R 8 reales KM 10
"Argentina - Republic. 8 Reales, 1840-R. Mountain peak, crossed artillery and pennants beneath. Reverse: Oval shield with hands holding liberty cap, wreath around, topped by radiant sun. Centers a bit soft, but bold for issue. Fields especially clean for this often wretched issue, with fine cartwheel luster. Warm, even old toning. Struck by order of the then governor of La Rioja, Brigadier General Tomás Brizuela, who was a long-time ally of Juan Manuel Rosas, then governor of the province of Buenos Aires - 'En Union y Libertad.' Brizuela's decision to rebel against federalist rule from Buenos Aires and Rosas' overbearing will and turn on his former ally led to the change in legend in KM 8 to the one visible in this specimen. The key silver coin of the Argentina series. NGC graded AU-58."
This type is much rarer than the La Rioja issue of 1838-40 (KM 8) which is much more affordable. It is referred to in Argentina's numismatic references as the "Unitarian" type, whereas KM 8 is referenced as the "Federal" type.
Recorded mintage: unknown.
Specification: silver, this specimen 27.65 grams.
Catalog reference: WR-5; Eliz-30; KM 10.
