20 Francs Belgium Leopold II (1867-1882) — the Belgian LMU 20F with the portrait of the king of the LMU founding state
The 20 Francs Belgium Leopold II (1867-1882) gold coin is a historic Belgian 20-franc piece of the Latin Monetary Union (LMU) standard with a gross mass of 6.4516 g, a pure-gold mass of 5.80645 g, a 0.900 fineness (Crown-Gold-style alloy), a 21.0 mm diameter and a 20-Belgian-franc face value. The obverse features the portrait of King Leopold II — the second ruler of independent Belgium (1865-1909) — with the inscription LÉOPOLD II ROI DES BELGES (Leopold II King of the Belgians).

Why Leopold II deserves a place in your portfolio
- Belgium as an LMU founding state — historic rank of the coin: Belgium was one of the four LMU founding states by the treaty of 23 December 1865 (alongside France, Switzerland and Italy). The Belgian 20-franc Leopold II adopted the LMU standard without modification — mass, fineness, diameter identical to the French 20F Napoleon III. Full interchangeability with the other 20-franc coins of the union was retained throughout the Leopold II mintage period.
- Portrait of the king of an LMU founding state — unique collector position: Leopold II of Belgium (reigned 1865-1909) is the only monarch of an LMU founding state whose portrait appears on a 20-franc coin during the active Union. Napoleon III (France) was struck until 1870 when the Second Empire fell; Helvetia and Vreneli (Switzerland) do not show monarchs (Switzerland is a republic). Leopold II in the period 1867-1882 is the only example of a monarch's portrait on an LMU 20F.
- Crown-Gold-style alloy 0.900 — LMU standard: The 900 fineness (Au 90% + Cu 10%) is identical to all LMU 20F coins. The alloy is harder than pure 999.9 gold, preserving the coins in good condition after 145-160 years of circulation. The Belgian Brussels Mint struck Leopold II in identical specifications to the Monnaie de Paris (Napoleon III, Angel) and the Bern Mint (Helvetia) — full LMU interoperability.
- Median premium 4-8% over spot — collector-investment compromise: Leopold II has a market premium higher than Vreneli (2-5%) and Napoleon III/Angel (3-6%), but lower than Helvetia (5-10%). Median premium of LMU 20F for Leopold II — neither the cheapest nor the most expensive option. Results from moderate mintage (several million pieces over 16 years) and the Belgian regional market smaller than the French or Swiss.
- Belgium as a young state (from 1830) — historic context: Leopold II (1835-1909) was the second king of independent Belgium, a state established only in 1830 after the revolution separating Belgium from the Netherlands. The Leopold II issues 1867-1882 document the early phase of Belgian statehood — a period of industrialisation, colonial expansion (Congo Free State from 1885) and consolidation of independent Belgium in Europe.
History of Belgium in the LMU and Leopold II's reign
Belgium emerged as an independent state in 1830 after the Belgian Revolution separating the country from the United Kingdom of the Netherlands (established in 1815 after the Napoleonic Wars). The first king was Leopold I of Saxe-Coburg (reigned 1831-1865), elected by the National Congress of Belgium from among German Protestant princes. Leopold I established the Belgian constitutional monarchy by signing the 1831 constitution — one of the most liberal in 19th-century Europe.
Leopold II of Belgium (1835-1909) ascended the throne on 17 December 1865 after the death of his father Leopold I. The first 20-franc coins of Leopold II appeared in 1867 — with a two-year delay relative to the accession, due to the need to redesign the royal portrait (Leopold II was already 30 years old at the time of coronation, so the portrait had to differ from his father's image from the 1830s). In total, Leopold II was struck for 16 years (1867, 1869-1882) — the break in 1868 resulted from a mint reorganisation.
Belgium joined the Latin Monetary Union as a founding state by the treaty of 23 December 1865 — only a few weeks before Leopold II's accession to the throne. The LMU 20F standard (6.4516 g gross, 0.900 fineness, 5.80645 g pure gold) was accepted for the Belgian 20-franc coin without modification — Belgium accepted the French pattern mathematically derived from the germinal franc. The Belgian franc was interchangeable with the French, Swiss and Italian at a 1:1 ratio — both in silver and in gold.
Léopold Wiener (1823-1891) — Belgian sculptor and engraver of Jewish-German origin — was the chief medallist of the Brussels Mint in the second half of the 19th century. Wiener designed the Leopold II portrait for the 20-franc coin in 1867 — the portrait remained in use throughout Leopold II's reign until 1882 (replaced thereafter by the "Pigeon" motif — peace dove — in the years 1882-1909). Léopold Wiener was also the author of numerous Belgian, Dutch and French medals and commemorative coins of the Kingdom of Belgium.
In 1882 Belgium withdrew the Leopold II portrait from the 20-franc coin and introduced the "Pigeon" motif — a peace dove instead of the king's portrait. The reason was Leopold II's collector strategy — the king did not want his portrait to continue being mass-struck as the period of colonial expansion in the Congo (from 1885) and the political controversies associated with it approached. The 20-franc Pigeon issues (1882-1909) are stylistically different from Leopold II and sold as a separate collector type.
Obverse — Leopold II by Léopold Wiener (1867)
The obverse of the 20 Francs Belgium Leopold II coin features the portrait of King Leopold II in left profile (or right in some issues), with hair styled in the Victorian period style and the characteristic sideburns (favourites) typical of 19th-century fashion. Around the portrait is the inscription LÉOPOLD II ROI DES BELGES (Leopold II King of the Belgians) — the French title of the monarch, official in the Belgian constitutional monarchy.
Léopold Wiener (1823-1891) — Belgian sculptor and engraver born in Hoorn (Netherlands) — was the son of the German engraver Jacob Wiener, who settled in Belgium after 1830. Léopold studied in Brussels and Paris, where he was a student of well-known French sculptors of the Second Empire period. At the Brussels Mint Wiener served as chief medallist in the years 1865-1890 — he designed hundreds of Belgian, Dutch and French medals and coins.
The Leopold II portrait by Wiener is stylistically close to the Napoleon III portrait by Barre — both artists derived from the French sculptural tradition of the second half of the 19th century. The contrast to the Swiss Helvetia (Bovy, classicist woman) and Vreneli (Landry, young woman with braided hair) is clear — Leopold II is a portrait of an adult, bearded man in Victorian style, emphasising the majesty of the monarch. The inscription DES BELGES (of the Belgians, in the genitive) — not DE BELGIQUE (of Belgium) — reflects the Belgian constitutional tradition: the king is king of the nation (of the Belgians), not sovereign of a territory.
Leopold II was known in 19th-century Europe for his tall stature (he measured approx. 1.90 m, significantly above the era's average), long beard greying in later years, and active foreign policy (creation of the Congo Free State in 1885 as his private colony). On the 20-franc coins from the years 1867-1882 Leopold II is still depicted without grey hair — he was then 32-47 years old. The absence of an older Leopold II portrait on 20-franc coins results from the withdrawal of this motif in 1882 in favour of the Pigeon — when the king was already 47 years old and his image could have been updated.
Reverse — Belgian heraldic shield with the Belgian lion
The reverse of the 20 Francs Belgium Leopold II coin features the heraldic shield of the Kingdom of Belgium — a black shield with a golden Belgian lion (lion rampant facing left or right) with a crown above the shield. Around the shield is the inscription L'UNION FAIT LA FORCE (Unity makes strength) — the national motto of Belgium since 1830, chosen by the National Congress after the Belgian Revolution as an expression of Walloon-Flemish unity in the new state. Below the shield are the face value 20 FR and the year of minting.
The Belgian lion (Léo Belgique) has been the national emblem of Belgium since the Middle Ages — it derives from the coats of arms of the Duchy of Brabant (the main component of medieval Belgium) and the County of Flanders. The lion rampant (standing on its hind legs) symbolises strength, courage and sovereignty — a traditional motif of European heraldry associated with medieval monarchies. The crown above the shield is the Belgian royal crown — designed in 1831 for Leopold I, used by all subsequent Belgian kings.
The motto L'UNION FAIT LA FORCE (Unity makes strength) has been the national motto of Belgium since 1830 — it expresses the idea of federal unity between the Walloons (French-speaking southern Belgium) and the Flemings (Dutch-speaking northern Belgium), the two main language communities of the newly formed state. The motto appears on state coats of arms, coins (the reverse of the 20-franc Leopold II coin), postage stamps and Belgian official documents. In the three official languages of Belgium the motto reads: L'UNION FAIT LA FORCE (French), EENDRACHT MAAKT MACHT (Dutch), EINIGKEIT MACHT STARK (German).
The year of minting placed under the shield serves as the distinguishing feature between issues in the 16-year Leopold II series (1867, 1869-1882). The most common vintages are the years 1874-1880 (highest mintages). The rarest are early issues (1867 — first production year, low mintage; 1868 no issue) and late issues (1881-1882 — twilight of the Leopold II series before the introduction of the Pigeon in 1882). These issues may have numismatic value higher than the precious-metal value — typically +20-40% over mixed years.
What to look out for when buying
Check the vintage of the Leopold II coin — in secondary trade, mixed years contains various vintages 1867, 1869-1882. Specific collector vintages (1867 — first production year; 1881-1882 — last issues before the Pigeon) may be sold with a numismatic premium of +20-40% over mixed years. For an investment strategy, mixed years are optimal — lower unit cost while maintaining full gold content (5.80645 g identical in all vintages).
Note the collector subtype — after 1882 Belgium struck 20-franc coins with the "Pigeon" motif instead of the Leopold II portrait — the 1882-1909 issues are sold as a separate collector type. Mixed years usually contains only the Leopold II portrait issues (1867-1882); Pigeon issues (1882-1909) are sold separately. When buying, check the type — Leopold II portrait vs peace dove on the obverse.
The market premium on Leopold II typically holds in the range of 4-8% over spot — the median among LMU 20F: higher than Vreneli (2-5%) and Napoleon III/Angel (3-6%), but lower than Helvetia (5-10%). Results from moderate mintage (several million pieces in 16 years of production) and a smaller regional market than the French or Swiss. Belgium is less numerous on the European secondary market than France or Switzerland, which raises the premium — but still significantly lower than on modern bullion or fractions.
Check the condition of the coin and authenticity — Leopold II in the 900/1000 alloy retains typical circulation traces after 145-160 years: light wear, fine scratches, natural surface patina. Pay particular attention to the preservation of obverse details — Leopold II's beard and sideburns are fine elements prone to wear, similarly to the Belgian lion on the reverse (fine heraldic details). For an investment strategy, VF and EF grades are acceptable. Each coin is delivered in a protective capsule or individual blister.
