Commemoration
Von Welsbach was selected as a main motif for a high value collectors' coin: the Austrian €25 Fascination Light. The reverse has a partial portrait of Welsbach on the left hand side. The sun shines in the middle of the green niobium pill, while several methods of illumination from the gas light from incandescent light bulbs and neon lamps to modern Light-emitting diodes spread out around the silver ring.
