Depicts a landscape highlighting the karst terrain typical of Aggtelek National Park, prominently featuring the Tornai vértő flower—one of Europe’s 100 rarest protected plant species. The inscription “NATIONAL PARK AGGTELEK” is positioned along the upper edge, while “TORNAI VÉRTŐ” appears in the lower left. The engraver’s privy mark is located in the lower right corner.

The Tornai vértő (Fumana procumbens subsp. magyarica) is a rare and endemic plant species that grows exclusively in the Tornai Karst, Slovak Karst, and Aggtelek Karst regions. This small subshrub, with its delicate yellow flowers, thrives in dry, rocky grasslands and on limestone outcrops, favoring sunny, south-facing slopes with sparse vegetation. Its extremely limited geographic range and fragile habitat make it a symbol of the unique biodiversity of karst landscapes and a priority for conservation efforts. In Hungary, it is strictly protected and carries a conservation value of 250,000 forints. Threatened by natural overgrowth, human activity, and landscape changes, protecting its environment and managing vegetation are essential for its survival. The Tornai vértő stands as a botanical treasure and a testament to the ecological richness of Aggtelek National Park and its surroundings.

Depicts a spotted salamander set within its natural environment. The inscription “SPOTTED SALAMANDER” appears above to the right, while “HUNGARY” is inscribed along the top edge. At the lower left, arranged in three lines, are the coin’s denomination, the word “FORINT,” and the mint mark “BP.” followed by the year of issue, “2025.”

The spotted salamander (Ambystoma maculatum), featured on the coin as the heraldic animal of Aggtelek National Park, is a striking amphibian known for its dark body adorned with bright yellow or orange spots running down its back. Native to parts of North America, it is often confused with the European fire salamander due to similar coloration, but they are different species. The spotted salamander spends most of its life hidden underground or under moist forest debris, emerging primarily during rainy nights in early spring to breed in vernal pools. Its appearance on the coin symbolizes the park’s dedication to preserving unique and sensitive species within its biodiverse karst ecosystem.
