The coin was produced with a mintage of 161,000 pieces and is officially backed by the government of Panama. The obverse displays the detailed national coat of arms of Panama, positioned proudly above the denomination. On the reverse, the design features a portrait bust of the historic military and political leader Simon Bolivar, with the year 1974 inscribed below. This issue is cataloged under the reference number KM 31.
