In 1878 the markka was tied to a gold standard, and 20 markkaa corresponded to 6.45 grams of a mixture containing 900 per mille of pure gold. The markka was of equal value with the French franc, the Belgian franc, the Swiss franc and the Italian lira (and later also with other member states of the so-called Latin Monetary Union). The size, weight and gold content of these coins was equal regardless of the issuing country and in theory, they were also legal tender regardless of the issuing country, even though gold 10 and 20 markkaa coins were struck in so small amounts compared to the other corresponding European coins that no significant numbers of these coins ever wound up in central Europe.
