How to Identify the Belgian 5 Francs

What This Coin Is

The Belgian 5 Francs is a large silver coin issued by the Kingdom of Belgium beginning shortly after independence in 1830, continuing through the reigns of Leopold I, Leopold II, and later monarchs in various metal compositions. Because Belgium has two main language communities, many dates were struck in both French ("BELGES") and Dutch ("BELGEN") legend versions, a bilingual practice that continued across much of the country's coinage history.

Obverse Design & Inscriptions

The obverse shows the bare or laureate head of the reigning king in profile, with his name and regnal title around the rim, such as "LEOPOLD PREMIER ROI DES BELGES" or "LEOPOLD II ROI DES BELGES." The engraver's initials often appear in tiny letters at the base of the neck.

Reverse Design & Inscriptions

The reverse typically displays the crowned Belgian national arms or a wreathed value, with "5 FRANCS" or "5 FR" and the date. Legend variants read either "L'UNION FAIT LA FORCE" (French) or "EENDRACHT MAAKT MACHT" (Dutch), both meaning "Unity makes strength," Belgium's national motto.

Size, Weight, Metal, and Edge

Early silver issues are large crowns around 37 mm and 25 grams in .900 fine silver, with a reeded edge. Some later 20th-century 5 Francs coins were struck in smaller sizes and base metals such as nickel or nickel-brass, so always check the coin's overall diameter and color before assuming silver content.

Mint Marks and Where to Find Them

Belgian coins generally do not carry separate mint letters since all official coinage came from the Brussels mint, but small privy marks (such as a lion's head or workshop symbol) may appear near the date to mark a particular die series or restrike.

Telling It Apart From Similar Coins

French and Swiss silver crowns of similar size can be confused with Belgian issues at a glance; check the national motto and the king's name to confirm origin. Also distinguish the French-legend and Dutch-legend Belgian varieties of the same date, since both exist for many years and are considered distinct types by collectors.

Judging Condition at a Glance

Look at the king's hair or laurel wreath and the fine feathers or fur on the coat of arms for wear; these areas flatten quickly with circulation. A coin with full luster in the fields and sharp lettering is in higher grade than one with a smooth, dull portrait, and any hairlines or scratches across the open fields should also be factored into an overall condition assessment.

Authenticity Red Flags

Be cautious of coins that feel unusually light, have soft or mushy lettering, or show a seam around the rim, all signs of cast counterfeits. Also verify the language legend matches known issue years, since mismatched wording can indicate a fantasy or altered piece.
