Watch List notes:

La Rioja, Argentina, 8 reales, 1840 R, "rebel peso," very rare, NGC XF 40 ("top pop"). Janson-58; KM-10. Very deeply toned and faintly lustrous, struck slightly off-center, with no issues for the grade, one of just two in the NGC census (same grade), a particularly rare and desirable one-year type with REPUBLICA instead of CONFEDERADA in legend, as struck by rebel leaders under General Brizuela, governor of the province of La Rioja, breaking from federalist rule and his long-time ally General Juan Manuel de Rosas (governor of Buenos Aires). This famous issue, the key to the Argentina crown series by type, is known in Argentina as the "unitarian" issue versus the normal "federal" issue of 1838-40.
