On the occasion of the 225th anniversary of the birth of István Széchenyi, the Magyar Nemzeti Bank will issue a silver commemorative coin with a denomination of HUF 20,000 and a non-ferrous metal version with a denomination of HUF 2,000 on September 21, 2016. The commemorative coins appear with an unusual denomination and size, as if reflecting Kossuth's description of Széchenyi: the largest silver commemorative coin (diameter 52.5 mm) is "the largest of the Hungarians". Another special feature of the commemorative coins is that their knurled edges are uniquely assigned, the grouping of the knurls refers to István Széchenyi's year of birth, thus giving content to the "third" side of the coin.
