Known as a “taksplaatje” (tax plate), these metal medallions were issued to bicyclists in Belgium from 1893 until 1991. The bicycle was seen as a luxury item at the time and therefore required those who wished to ride one on Belgium’s roads to pay tax. The tax levied at the time, 10 Belgian francs (Bfr.), stood in stark contrast to the common worker’s 2 Bfr. salary at the time.H37
