  3. cleaning /storing coins

    in Coin Forum

    Posted

    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? ;)

  12. Some value comparisons

    in Coin Forum

    Posted

    :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... :|

  15. Super XXL Soviet 5oz silver medals x4!

    in Exonumia (Tokens, Medals, etc) Forums

    Posted

    Produced together in coperation with the Soviet Leningrad mint and American Bullion and Coins in 1988, this is one massive set and heavy. All of them are 5oz each!!!

     

    The coins / medals represent the level of cooperation that had begun between the USSR and the United States in those years. Each coin / medal represents issues of cooperation and freedom in the USSR.

     

    1. Peace and Cooperation

    2. INF Summit Treaty Medallion

    3. Millennium of Christianity

    4. Thousand Years of the Ruble

    Warning: super large images! :ninja:

     

    Front Image

    Back Image

     

    Appearently, the INF amd the Christianity medals were presented to both President Reagan and General Secrarty Gorbachev. ;)

     

    The forth medal served a prototype of the first Soviet silver commemorative coin, which is used in the design of the 1,000 years of the mintage of Russian coins.

     

    All these are considered pretty rare, considering all of them except the Peace and the Cooperation medal had a scarce mintage of 1,000 and the "polar bear" one had a mintage of just 10,000.

     

    P.S. The Polar bear medal is one of those rare times when an American and a Soviet medallist designed this medal. ;) Obviously, the American designed the polar bear side... :lol:

     

    Hope you enjoyed it :cry:

  16. Russo-Polish coins

    in Nicholas I 1825-1855

    Posted

    (continued)

     

    This particular coin that I have is pretty funny. Notice how the last digit "5" of the year 1835 is slanted off? It seems that a massive amount of dies were produced with the date "183", and leaving the last year to be fixed later, which probably explains the tilt.

     

    The obverse seem to have been hinged somehow, as you can see two tiny shouldered parts on the word "DO/\EU" and "4UCTO|-O" (i'm sorry, I am a bit too lazy to type out cyrillic atm... ;)) But fortunately, there are NO major damages... ;) And also I got this coin bloody cheap too :ninja:

     

    Nevertheless, there is an major error, if you didn't notice, which is an offstrike error. Pretty hard to find errors in this type of coin, as Russian coinage are supposed to be almost perfected at this time.

     

    There is also an edge error, which is pretty suprising. :lol:

     

    Here are a few super large image files for you to enjoy :cry:

     

    Caution: Massive size pictures!

    Edge error: edgeerror1tb.jpg

     

    See how there is a double effect after the "o"? :D

     

     

     

    Ok, if you didn't manage to see where the error on the reverse has happened, here it is :D

  18. Russo-Polish coins

    in Nicholas I 1825-1855

    Posted

    During Nikolai I's period, a very rare event occured, which made history in the numis. history of both Russia and Poland.

     

    The first coinage of the occupied Poland goes as far back to 1815, and in around 1830, there were some Polish rebels that tried to declare their independence, however, they were crushed ruthlessly and hence, there was need of a dual denomination to remind the Polish that the Russians are there. (pretty evil isn't it?)

     

    Polish coins

     

    Neverthless, the Russians tried to fix the exchange rates, which is then fixed to 3 rubles to 20 zlot, 1.5 rubles to 10 zlots, and so on.

     

    There were several denominations, which both silver and gold coins were minted. (no copper coins though)

     

    The denominations are as following: 3 rubles-20zlot (gold), the rest are silver: 1.5 rubles-10 zlot, 3/4 rubles-5 zlot, 30 kopeks-2 zlot, 15 kopeks-1zloty minted till 1841 and after 1841, only 25 kopeks-50groszy, 20kopeks-40groszy were minted.

     

    Both the Saint Petersburg mint (denoted as H|-) and the Warsaw mint (denoted as MW) minted the coins, but Saint Petersburg mint stopped minted in 1841, letting Warsaw to mint after 1842. Warsaw mint was later renamed to B.M. to mint copper coins after 1850.

     

    Alas but not least, this is an example of the LARGEST silver coin ever minted in the Russian silver coin, and also the largest denomination of silver rubles (excluding trial coins :ninja: )

     

    1.5 ruble - 10 zlot 1835

    Edge: SIL(VER) OF 83 1/3 STANDARD 7 ZOL(OTNIKS), 27 21/25 PAR(TS)

    Ripped out from Uzedenkov, Russian coins 1700-1917, this is a rather decent book to read. ;)
