Depicts the portrait of János Irinyi. The texture of the attire is repeated in the inscription "THE INVENTOR OF THE EXPLOSION-PROOF MATCH WAS BORN 200 YEARS AGO," in micro-sized letters. Along the edge, "IRINYI JÁNOS" is inscribed at the top, while on the left side, parallel to the edge, the birth and death years "1817-1895" are placed. The engraver's privy mark is visible on the left edge.

Depicts a burning matchstick, explosion-proof match flame on the side of a matchbox. The flame of the matchstick alternates with the colors of the rainbow in natural light and shifts with movement. On the left side, separated by a horizontal matchstick along the centerline of the commemorative coin, the denomination and the inscription "FORINT" are visible. Along the edge, "HUNGARY" is written at the top, while at the bottom left, the year of issue "2017" and the mint mark "BP." are placed. In the mint mark, micro-inscriptions become readable under at least tenfold magnification.

The Irinyi-type of match, commonly known as the "safety match," ignited when rubbed against a specially prepared surface containing red phosphorus. Unlike the earlier "strike-anywhere" matches, which could ignite spontaneously and sometimes caused accidental fires, Irinyi's matches required deliberate friction against the designated surface to light, making them safer to use. This invention significantly improved the safety and reliability of matches and had a profound impact on daily life and industry.
