Production of 2 centimes ended in 1919.
In 1922 and 1923, nickel 50 centime and 1 and 2 franc coins were introduced bearing the text "Good For" ("Bon pour" in French, "Goed Voor" in Dutch).

Nickel 5 and 20 francs were introduced in 1930 and 1931, respectively, followed by silver 20 francs in 1933 and 50 francs in 1939.
In 1938 the 5 franc was reduced in size and redesigned along with the 1 franc to depict a lion and heraldic arms.

As a consequence of the German occupation in 1940, the silver coinage was discontinued.
In 1941, zinc replaced all other metals in the 5, 10 and 25 centimes, and 1 and 5 francs.
In 1944 the Allies minted 25 million 2 franc coins at the Philadelphia Mint using leftover planchets for the 1943 steel cent.

In 1948, cupro-nickel 5 francs and silver 50 and 100 francs were produced, followed by silver 20 francs in 1949 and cupro-nickel 1 franc in 1950.

The 25 centime coins were later discontinued in 1975.

Aluminium-bronze replaced cupro-nickel in the 5 franc in 1986, whilst nickel-plated iron replaced cupro-nickel in the 1 franc in 1988, which was also significantly reduced in size.
These changes coincided with a gradual modernization of the general coinage while older issues were gradually pulled from circulation, similar to what took place during the early postwar years.
The new designs were also more identifiable to vending machines and the visually impaired.
1994 saw a redesign of all denominations but the 50 centimes, with a uniform design featuring King Albert II replacing the image of Baudouin.
This series ceased production after 2000.

Coins ceased to be convertible in 2004.
