There were only  France, Belgium, Italy and Switzerland, but many other countrys also used the same spezifications of coins.
If you want them all, it's a really hard to achieve goal, because there are like more than 70 different types of the "20 Francs" size..

Two recent (raw) auction buys, now graded. 
 

cross-post from "today i received"
 
eceived recently :  3 coins
1- Austria-Hungary 20 Francs /8 Forint 1890 - features an eagle , from Fiume region , only present on some 1890 1891 & 1892.

 

 
2- Kingdom of Serbs , Croats and Slovenians ( a brief kindgom preceding Yugoslavia)  20 Dinara 1925 


 
3- 10 Francs - Switzerland - 1922 
 

Here are my recent additions.   I'm especially satisfied with the Belgian piece since I bought it at only 6~7% over melt,  but the condition is fabulous.   It looks better than my MS63 graded 20 Lei piece.

Now I have more than 3oz's of pure gold only with LMU '20'  denominations.   I don't like slabbed coins because I can't see the edge of the coins, which is a very interesting part for me.

That 1879 is a great looking coin!

Made some pictures today when I visited my coins in the Bank.
Very bad light in the basement so the pictures didn't come out very well. In real they look alot better.

Belgium 20 franc, really like this coin 🤠

Slight objection to 'eastern' - after all, Finland was a part of Kingdom of Sweden far longer (from 13th through more or less the 18th century). It was 'only' from 1809 to 1917 that Finland was designated as Grand Duchy of Russia. 😊🇫🇮 Finland legislated gold standard already in 1877 where as Russia stayed in silver standard for another 20 years. 
The coin above was minted from 1878 - 1913 in 10 markkaa and 20 markkaa denominations (see mintages below). Finns rather endearingly and literally wrote the composition on the 20 markkaa coin: 5.806 grams of gold (=kultaa) and 0.645 grams of copper (= kuparia).
Later there was another pair of gold coins (100 and 200 markkaa) issued only in 1926 - really lovely ones these, too. (edit: note these were heavier than the 10 and 20 markkaa LMU coins => AGW 0.1218oz and 0.2437oz, respectively).
The below text from Finnish to English through Google translate, apologies for somewhat poor grammar. 😉
Finnish gold coins
In May 2018, 140 years will have passed since the first gold coin was struck in Finland. The rapid decline in the price of silver in the late 1860s had made it difficult to maintain the silver standard in most countries. In Finland, the gold standard was introduced by a law passed in 1877, and at the same time the peg between the Finnish markka and the Russian ruble was broken. Financially, this meant convergence with Western Europe and distancing from Russia, which remained in the silver standard for another 20 years. There was also a distinct break from Russia's coinage in that the denominations of the coins followed the French example, the French gram measure was used and the weight and gold content of the coins (90%) were the same as in France. The compromise in the direction of Russia on the emblem of the 10 and 20 markkaa coins was the Russian imperial double eagle on its heart shield as the lion coat of arms of Finland. The only Finnish coin of the time, the country's name “FINLAND SUOMI” was written on the emblem. The reason for this was the requirements for the international convertibility of coins.
During the period of autonomy, the appearance of gold coins remained almost the same until the last gold coins minted in 1913 (photo). This was also important from the point of view of national self-esteem, as Russia itself switched to using the image of the ruler on its coins instead of the coat of arms in 1886. Finland did not follow this example, because by then the appearance of Finnish coins had already become established. The mintage of Finnish gold coins increased significantly in 1912, when Russia began to demand that Finnish payments be made only with Finnish gold coins. This also meant large investments in the mint’s capacity. The Finnish gold coins of 1878-1913 were not used very much in the normal money circulation. This was due to the large denomination of the coins, and larger shops preferred to use banknotes. About 10% of the volume of banknotes was in circulation during the period. The low circulation of gold coins can be attributed, at least in part, to the fact that gold coins are still generally in good condition and quite indelible.
However, at the beginning of the First World War in 1914, the global gold standard ended, in Finland the gold standard officially ended in 1915. In the years following independence, the value of the Finnish markka weakened at its worst to more than ten times lower than before the World War. When the value finally stabilized, it was decided to return to the gold standard in Finland in 1926. Gold coins were minted again in Finland in the same year as a sign of the gold standard. Now the denominations were 100 and 200 markkaa. Only about 50,000 coins were struck, and they were mostly of symbolic significance. Coins were not used in everyday trading. Unlike the previous gold standard, banknotes were no longer redeemable in gold either. The 1926 gold coins were originally designed as early as 1918, albeit at ten times lower denominations. In order to fit the larger denomination into the coins, the numbers had to be partially superimposed on the coins.
The return to the gold standard was due to the high inflation of the markka after the First World War. The gold standard sought stability for the value of the markka. However, the second gold standard remained short-lived. Finland plunged into a recession in 1928, which deepened in the stock market crash on Wall Street in 1929. The situation continued to deteriorate until 1931, when it was decided to temporarily abandon the gold standard and devalue the markka. This followed the example of an important trading partner, the United Kingdom. However, the temporary abandonment became permanent, and after 1931 Finland has not returned to the gold standard.

I finally received my Austrian coin.   It's interesting that although it's issued from the same country at that time,  even the edge is completely different. 
Both of them weren't intended for internal circulation because  Austro-Hungarian empire  was at the silver standard before 1892 and  the international price of silver was rapidly declining after 1873 so it was impossible to use gold due to Gresham's Law.    They were probably used as a trade coinage against LMU countries.   
 

Here is my recent purchase. https://www.ebay.com/itm/20-francs-coin-8-guilders-gold-Austria-1878-superb-condition-6-46-grams-/283987366861?nma=true&si=TdpQPk8xXbJ%2FcMfsrg9iXrKoSs4%3D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557
I had some trouble founding a non restrike(1892) version of this.  It will be an attractive set with my  Hungarian version.    I will immediately post my own photo as soon as it arrives.

Not sure if we have featured finnish 20 Markkaa yet; as all eastern european ‘LMU’ coins these carry more of a premium.


maybe @Xander can post pics of his 7 1/2 Roubles?
