Belgian 100 francs 'four kings' (silver)
Belgium · silver · 1948-1954
Overview
The Belgian 100 franc silver coin known as the 'four kings' was struck from 1948 to 1954. Its obverse superimposes the profiles of the first four Kings of the Belgians, Leopold I, Leopold II, Albert I and Leopold III, hence its nickname; the reverse carries the crowned arms of the kingdom and the value. It exists with legends in French and in Dutch, both versions struck to the same characteristics. The coin weighs 18 g of 835 ‰ silver, that is 15.03 g of fine silver, with a diameter of 33 mm. Very widespread in Belgian families, where it was often set aside as soon as it left circulation, it reaches the counter in variable condition, sometimes cleaned, which does not change the metal; it trades by its fine silver weight. At Gold & Silver Company in Dottignies, every four kings 100 francs is weighed and appraised in front of the person, like the gold coins; the assay in the agency is what counts.
