  1. Commemoration of the 70th anniversary of the Great October Socialist Revolution87revolution01xa.jpgThis is part of the Government issued proof sets available. While it may seem pretty easy to find one, this may not necessary be true. :ninja:87revolution14ke.jpg87revolution24fc.jpgMinted all on the same date, 20.10.1987 by the Leningrad Mint

  2. I just typed out a list of major mints that used to mint Russian coins and related so forth.

     

    Reference used is Uzedenikov. :ninja:

     

    1. Moscow Mints

    - Red - struck most of the gold, silver and copper coins from 1701-1737

    - Kadashevsky - Struck copper coins from 1699-1727

    - Naberezhny copper

    - New - Struck silver kopeks from 1700 - 1718.

     

    Mint marks: generally MMD, for moscow mint.

     

     

    2. Saint Petersburg and suburbs:

    - St. Petersburg - struck all denominations from 1724-1728, 1738-1798, 1806-1917.

    This mint has produced almost of all Russia's coins, including trial coins, such as platinum coins, trial nickel coins, and even major forgeries of the Dutch gold dutch and Turkish paras. Created dies for other mints as well. This mint had strong connections with other major international mints, such as the Paris, Strasburg, Brussels, Birmingham private mints and Osaka mints.

     

    - Sestroretsk - one of the major mints that had new technology at that time to smelt copper out from bronze cannons. It operated from approximately 1757 - 1778. In 1770-1778, there was several attempts to create "Sestroretsk" ruble coins out from raw copper from this mint. It failed horribly because such coins were too heavy and difficult to create.

     

    - Kolphino - Operated from 1810-1821. Used mintmarks of I.M ("reverse N", M) and operated for a shortwhile from 1840-1843.

     

    Mint marks: Generally CIIb, for Saint Petersburg mint.

     

    3. Ekaterinburg - 1727-1876. The only reason why there was a mint from Ekaterninburg is because Ekaterninburg is full of natural resources and it still does up to now. In 1725, striking of copper "plates" coins, inspired by the Swedish copper plates was tried out, but it was not terribly successful. Ekaterinburg used to mint copper coins, and later supplied copper planchets for Moscow Mints. Ekaterinburg's minting technology was pretty far behind compared to both Moscow and Saint Petersburg, and this could be told from their crude strike, which still existed until the late 1820s. Mintmark for this mint is denoted by E.M.

     

    4. Anninskoye - 1789 - 1798. Struck various copper coins and they took part in the 1796 overstriking event. Mintmark was denoted by AM.

     

    5. Suzun - 1766 - 1847. One of the remote mints that strucked Siberian coins till 1781. It continued resuming minting coins 1830 marked coins with the mintmark "KM" and then later on with "CM"

     

    6. Tiflis - 1804-1834. (located in Tbilisi, Georgia) Struck silver and copper coins for Georgia.

     

    7. Tauric - Operated just a short two year, 1787-1788. Struck copper coins and possibly silver coins, but we do not know for sure. This is one of the mysterious place that coins were minted in Pheodosia.

     

    8. Warsaw - Operated from 1816 - 1864, when Poland is still part of Russian terrority. Coins from 1834-1850 were struck with the historical dual denomination. Mintmarks were MW from 1816-1850, but they were later changed to BM for "B"arsaw Mint, as there is no "W" in Russian.

     

    9. Helsingfors - Operated from 1863-1917, located in Helsinki. Without much saying, this mint minted gold, silver and copper coins for Finland with a complete set of their own design, except for the Nikolai II and the double headed eagle.

     

     

    There were some foreign mints that were involved with the Russian coinage.

     

     

    Paris mint: In 1861, 20, 15 and 10 kopecks coins were minted in Paris. Although they have the same mintmark as CIIb, they do not have the mintmaster initials.

     

    Some of the 1896, 1898, rubles, 1896, 1897 and 1899 50 kopecks were minted in Paris. Some of the rarer gold coins such as the 1896 25 rubles and 1902 37.5rubles-100 francs were minted there too. Paris mints marked their designs on their edge by an asterisk.

     

    Brussels Mint: It strucked the same 1897-1899 rubles, like the Paris mint, but they are noted by their marks on the edge of the coins, which is either a double asterisk, or double ticks.

     

    This mint too minted trial 1863 2 kopeks coin in nickel and copper with the mark of EM.

    They also minted trial nickel and copper coins of the 10 kopecks 1871 series.

     

    Stockholm mint: Strucked trial coins for Finnish trial coins in 1863. No mintmarks.

     

    Osaka mints: Strucked some of 1916 15 and 10 kopeks coins and possibly trial 1916 NICKEL coins. These could only be told by their absence of the mintmaster marks.

     

    Private mint in Birmingham - struck copper coins of all denominations from 1896-1898. There is no indictions of the differences from the Russian ones.

     

    Sadogura estate: Minted coins for Moldova and Wallachia from 1771-1774.

     

    Avesta mint: Sweds were counterfeiting Russian 5 kopek coins as copper revolutionary prices were profitable and so these were done in major scales. In 1788, a large mass of counterfeit Catherine II 5 kopeks coins were found. These are usually dated by 1764, 1778, 1787.

     

    Berlin & Hamburg mint: Germans struck steel 1, 3, 5 kopek coins for the German occupied Russian land.

     

     

    Hope you enjoyed reading it. ;) I might have missed some out... so feel free to reply. ;)

     

    P.S. There ARE a variety of mintmarks, such as MMD, MM or MD for Moscow Mint, or CIIb or CM

  3. Indeed, that is true. You can find German coins easily, but the question is, if you want to assemble a whole set, you are probably looking at more than some... I guess 200+ type of coins easily? (excluding all the common dates, etc)

     

    I mean, the only reason why Germany has so many different types of coins is only if you included all the previous German states, which makes it quite impossible to collect... :|

     

    I have seen a German coin catalogue and I just gave up collecting German coins after seeing how many there are. :ninja:

  4. From the book "Russian coins" by Uzdenikov. Enjoy :ninja:

  5. I read in a German forum that a several 9999 german gold coins had red spots

    A university investigated them with X rays and established the spots were

    84 % silver 10 % copper and 5 % gold and were probably silversulfide

    It was assumed the spots were only a few molecular layers thick and were impurities of the planchet makers who made silver blanks and gold blanks

     

    So assuming my coin is spotted not with acrylic paint but with silversulfide I seam to find that one of the possible treatment is citric acid µ

    I know nothing about silver any suggestions ?

     

    Yuck, that is very horrible. Must be some horrible silver/copper plating devices used to strike the gold coins. Bad quality checking. :ninja:

     

    Citrus acid wouldn't necessary help, as it may dissolve some of the copper away, but it will not do anything with the silver. I was about to suggest nitric acid, but I REALLY don't know the results, as it does seperate the silver off from gold too but I don't know how the final result would be like... ;)

     

    Geez, what kind of coin do you have there ageka? ;)

  6. :S I can't tell without the column, it's pretty hard to tell :ninja:

     

    But I am assuming that you are trying to compare between 1956 to 1996...? Seems like the average is like at least 5 fold increase or so... for most of them, if my eyes are right... Probably the coins increase their value by about 8-10% per annum... or so... :|
