| Obverse description | The central field features a geometric diagram drawn from János Bolyai's foundational work on non-Euclidean geometry, depicting a circle with intersecting dashed and solid lines, labelled with algebraic variables including a, c, u, n, and s, illustrating the construction of hyperbolic geometry. The design is rendered in a precise, engraved style against a smooth, mirrored proof field. The circular legend around the upper periphery reads MAGYAR KÖZTÁRSASÁG, while the lower arc bears the mint mark BP., the denomination 3000 FORINT, and the date 2002. |
