Few coins sit as comfortably at the intersection of history, beauty, and value as the 20 franc gold piece. Struck across multiple European nations throughout the 19th and early 20th centuries, these coins circulated as real money during some of the most consequential decades in Western history \u2014 the Napoleonic wars, the Belle \u00c9poque, two world wars, and the rise and fall of the gold standard.<\/p>\n\n\n\n

Latin Monetary Union context: <\/strong> Formed in 1865 by France, Belgium, Italy, and Switzerland, the LMU standardized coinage specifications so that a French 20 franc, a Swiss 20 franc, a Belgian 20 franc, and an Italian 20 lire were all interchangeable. This is why collectors today can build a unified \u201c20 franc\u201d collection spanning multiple nations and designs.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The Four Major Types Every Collector Should Know<\/h2>\n\n\n\n

1. Napoleon (France, 1803\u20131870)<\/h3>\n\n\n\n

The coin that started it all. Napoleon Bonaparte introduced the 20 franc gold piece<\/a> in 1803 as part of his sweeping monetary reforms, and the denomination would carry his name \u2014 Napol\u00e9on<\/em> \u2014 long after his empire fell. Three distinct portrait styles span the series: Napoleon I as First Consul and Emperor (1803\u20131815), the brief restorations of Louis XVIII and Charles X (1816\u20131830), and Napoleon III\u2019s Second Empire (1852\u20131870).<\/p>\n\n\n
