Why Investors Worldwide Are Turning to Historic Trade Gold Coins
By StoneX Bullion
For centuries, gold coins have been the very embodiment of value and stability. Long before modern bullion coins such as South Africa’s Krugerrand, Canada’s Maple Leaf or Austria’s Vienna Philharmonic conquered the market, historic trade gold coins dominated international payments. They were minted in large numbers, served worldwide as money in everyday circulation and were at the same time an instrument of international commerce.
Today these coins are experiencing a renaissance. Increasingly, investors are looking not only at new bullion issues, but at classic trade gold coins such as the Swiss Vreneli, the French-Belgian 20 francs pieces, the Dutch 10 gulden, the Austrian 100 corona or the American Double Eagle. They are comparatively affordable, robust and possess a historical dimension that modern investment coins cannot match.
The specific advantages of historic trade gold coins
These coins offer investors a range of advantages. A central aspect is price attractiveness. Trade gold coins are usually traded with very small premiums over the pure gold price. This is because they exist in large quantities and are characterised by a standardised composition. For investors this means they can buy close to spot, whereas modern bullion coins often carry slightly higher minting premiums.
A second advantage is robustness. While modern investment coins such as the Maple Leaf are struck in fine gold at 999.9 parts per thousand and are therefore sensitive to scratches, classic trade gold coins are mostly made from a gold-copper alloy of 900 or 917 parts per thousand. This hardness made them suitable for circulation and means that even after decades of use they remain sturdy and easy to trade.
In addition, these coins offer a historical and cultural dimension that modern bullion coins cannot provide. Anyone who owns a Vreneli or a Double Eagle holds a piece of monetary history in their hands. They speak of times when gold was not only an investment vehicle, but the backbone of the global financial system.
The Latin Monetary Union: a European precursor of the euro
Many of the best known European trade gold coins owe their existence to the Latin Monetary Union, founded in 1865. France, Belgium, Italy and Switzerland formed a currency union that later admitted further members such as Greece. The goal was to create uniform coinage standards so that gold and silver coins could circulate across borders on an equal footing.
The central principle was standardisation. A 20 francs piece from France contained exactly the same amount of gold as a 20 francs piece from Belgium or Switzerland. The fine weight was 5.81 grams, the fineness 900 parts per thousand. This harmonisation made the coins a kind of nineteenth-century “euro”. They could circulate without exchange in all member states and facilitated international trade.
The Latin Monetary Union was therefore not only a milestone in monetary history, but also a model for today’s currency unions. For investors the benefit persists to this day. Coins from different countries are comparable and equivalent. Anyone investing in 20 francs pieces receives standardised units of value that are recognised worldwide, regardless of the country of origin.
The Swiss Vreneli: a national symbol
Perhaps the best known of the trade gold coins is Switzerland’s 20 francs Vreneli. Between 1897 and 1949 more than 58 million pieces were minted, with restrikes in the 1950s. The Vreneli is therefore among the most widely issued European gold coins.
The obverse depicts the “Vreneli”, a young woman with plaited hair and an Alpine landscape in the background, an embodiment of Swiss identity and closeness to nature. The reverse bears the Swiss cross within a radiating wreath. With a weight of 6.45 grams and a fine gold content of 5.81 grams, the Vreneli conforms to the standards of the Latin Monetary Union.
For investors, the Vreneli is particularly attractive because the huge mintage ensures easy availability and international familiarity. Collectors also value certain years that were struck in smaller numbers. The Vreneli thus ideally combines investment and collector appeal.
French and Belgian 20 francs: unity in diversity
Another mainstay of the Latin Monetary Union is the 20 francs pieces from France and Belgium. They bear different motifs, in France for example Napoleon III, the “Génie” or the Gallic cockerel, in Belgium King Leopold II, yet all are based on the same specifications, 6.45 grams total weight, 5.81 grams fine gold and 21 millimetres in diameter.
The enormous distribution of these coins makes them a popular choice for investors to this day. They are often referred to as “Napoleons”, even though they do not exclusively depict Napoleon III. The advantage lies in the ease with which investors can switch between French, Belgian, Swiss or Italian issues, since they are essentially identical.
It is precisely this interchangeability that makes 20 francs coins attractive to investors. They are recognised worldwide as investment gold, can be compared easily and at the same time offer historical variety.
The Dutch 10 gulden: regal and compact
The Dutch 10 gulden were minted between 1875 and 1933 and are among Europe’s classic trade gold coins. The obverse shows Monarchs Willem III or Queen Wilhelmina, the reverse the Dutch coat of arms.
With a fine gold weight of 6.05 grams, they bring slightly more gold content to the scale than the 20 francs pieces, while fulfilling the same purpose, standardised trade gold coins accepted across borders. Today they are readily available in the investment trade and are appreciated by investors who prefer smaller denominations.
The Austrian 100 corona: a Habsburg legacy
Austria-Hungary struck large gold coins at the beginning of the twentieth century with a face value of 100 corona. The best known issues date from around 1912 and show Emperor Franz Joseph I with a laurel wreath.
After the monarchy collapsed, these coins were no longer used in circulation, but the Austrian Mint reissued them as restrikes dated 1915. These restrikes are still available on the market today and are among the most popular European trade gold coins. With a fine weight of 30.49 grams, they are among the largest classic denominations and are therefore particularly attractive for investors who wish to bundle larger amounts of gold in a single coin.
The American Double Eagle: gold on a grand scale
Beyond Europe, the 20 dollar Double Eagle is the best known example of a historic trade gold coin. It was minted in the United States from 1849 and contains 0.9675 troy ounces of gold, almost a full ounce. The series exists in two main types, the “Liberty Head” and the famous “Saint-Gaudens” design that circulated from 1907 to 1933.
The Saint-Gaudens issue in particular is considered by many to be one of the most beautiful coins in the world. Its artistic ambition sets it apart from other trade coins. For investors the Double Eagle offers not only a high precious metal content, but also collector potential.
Why investors are returning to trade gold today
Rising demand for historic trade gold coins has several causes. First, they offer a low cost route to physical gold, since premiums are often lower than on modern bullion issues. Second, they are robust and practical, because they were originally intended for circulation.
There is also the emotional added value. A Vreneli or a Double Eagle is not only an investment, but a historical artefact. Such pieces connect investors with a time when gold was the foundation of the world financial system. Especially in periods of geopolitical uncertainty, many investors consciously turn to these coins because they exude confidence.
Historic gold with a bright future
Historic trade gold coins are more than a low cost alternative to modern bullion coins. They combine precious metal value, stability and cultural significance. Whether Swiss Vreneli, French and Belgian 20 francs, Dutch gulden, Austrian corona or American Double Eagles, all these coins are witnesses to an era when gold was the backbone of world trade.
For investors who see gold not only as a metal but also as a cultural asset, these coins are an ideal addition to a portfolio. They unite the security of a store of value that is thousands of years old with the vitality of history, and that is precisely where their special appeal lies.
