|Casinos Nacionales Argentinos was a public group of casinos which opened under the control and responsibility of the Central Government. Some of the most remembered casinos were opened in cities like Mar de Ajó, Necochea, Monte Hermoso, Miramar, Pinamar, Sierra de la Ventana, Tandil and Mar del Plata.
Chips issued by CNA kept the same design among all the casinos under its control and were widely used during the 80's, before the re-appearance of Peso as national currency by the beginning of the 90's. Additionally, due to the continuous economic changes caused by inflation and hyperinflation that hit the country during that decade, CNA decided, instead of printing exact values, as you can see in some of the plaque listings, to print alphanumeric designations, like "A3" - "B4" and so on, for which the value would change
according to the current economic reality of the country. Chip/jeton/plaque value information was disclosed by the casino once visitors arrived to gamble at the casino.
