The Nicaraguan national coat of arms occupies the central field, depicting a equilateral triangle enclosing five volcanoes rising from the sea beneath a radiant rising sun, with a Phrygian cap above. The legend REPUBLICA DE NICARAGUA arcs along the upper periphery in Latin characters, while AMERICA CENTRAL curves along the lower periphery, both separated by decorative dashes. The date 2020 appears in the exergue below the triangle. The entire design is bordered by an inner ring of evenly spaced raised dots. |

A highly detailed dorsal view of a Paslama sea turtle (olive ridley, Lepidochelys olivacea) fills the central field within a raised inner circle, its intricately engraved carapace rendered with stylized scutes and both fore-flippers extended laterally. A mint mark in the form of a stylized CF monogram appears above the turtle near the upper field. The legend TORTUGA PASLAMA arcs along the upper periphery, while the inscriptions 1 ONZA to the lower left and 10 CÓRDOBAS PLATA PURA curve along the lower periphery, indicating the denomination and fineness. |

Nicaragua's Paslama turtle — more commonly known outside the country as the olive ridley sea turtle — became the subject of significant conservation attention in the late twentieth century after nesting populations on Pacific beaches like Chacocente were found to be in steep decline due to poaching and egg harvesting. The species stages mass synchronized nestings called arribadas, a behavior that made entire populations catastrophically easy to exploit before protections were established.
KM#146 belongs to Nicaragua's ongoing bullion and commemorative silver program administered through the Banco Central, which has used the 10 Córdobas denomination repeatedly for .999 silver issues nominally tied to wildlife conservation themes.
