1974 100 Pesos Bicentennial

I'm not entirely certain about a 1974 100 Pesos coin specifically commemorating the May Revolution, as Argentina's major issues for that event typically align with anniversaries like the 1970 series for the 160th or the 2010 bicentennial. If it exists, it might be part of the broader commemorative gold series from the 1970s, possibly linked to national events under the military government. These coins were struck in 900 fine gold, weighing around 8.5 grams, and featured designs with historical motifs, though records on exact mintage could have been affected by later archival losses. That said, any such coin would reflect the era's economic instability, with gold values fluctuating wildly. It's a straightforward piece for collectors, not the stuff of legends. One odd note: in numismatics, we sometimes joke that these coins outlasted the regimes that issued them—briefly.
