These questions are almost going to be left unanswered because of the level of difficulty and lack of numisatic material. If you can answer any one of these, I will be shocked.
I did post similar questions in other boards; if you did read them before, I sincerly apologize for wasting your time :P
The following are all Russian coins so far... I have a little bit more to come if you wish :P
1st question: Massively overweight 1769 5kopek monster coin - a serious error or mintmasters having too much vodka during the winter???
As you can see, this coin is ridiciously too thick of 5.5-6mm and 4cm diameter. Of course, the gross weight will come out to be horribly overweight - a weight of 76.4grams where a similar 5 kopek coin is supposed to be around 40-50grams. Do note that this is much heavier than a Siberian 10 kopeks, which is around 65.52grams. There aren't any heavier Russian coins except for the heavy square plates and the Sestroretsk ruble but those rarely circulated.
Now what do you think? An error like this is too ridicious and the heaviest for this time I have come across is at maximum 60grams but nothing hitting over 70grams. This is not a fake 5kopek either as the amount of corrosion seems to be consistent of such coins minted in that era. Do note that 76.4grams is a generous 50%+ of the level of copper allowed to be a 5kopek, and also do remember that coins around that area were minted upon their metal values.
You see, this error is too ridicious as it would have passed through too many "checks". I mean even if this was done in the 1700s, this is too ridicious. Firstly you have the planchet that's too thick. Next you have the mintmasters not noticing how thick this is. And when it comes to quality checking, perhaps this one was inside a pile of underweighted 1769 5kopeks and when weighted in whole, must have passed the weight control test. My only reason to explain the whole process is the result of too much vodka party...
What do you think? :P
2nd coin: Genuine Prototype of democratic Russia 1992 100 rubles or just some ridicious fantasy?!?!?!
Sorry, I decided to make the scan black and white just in case some silly scammer decides to use the image and 'sell' it :P
This was done on two seperate planchets and interesting, I don't know what to say. This design is quite similar to Russia's 1 ruble "The Anniversary of the State Sovereignty of Russia" design.
The link is here: Link
As you can see, the design seems to be somewhat similar but there are several points to be made. We can assume that this might be some ridicious fantasy.
Some aspects on the reverse:
1) there are no such Catheral minted with a gold 100 ruble denomination.
2) there is the mintmark of MMD, or Moscow mint which is the traditional mint ever since the Soviet era that gold coins were to be minted there
3) Specific denomination of the gold content and mass weight are included and the font is consistent with the previously minted Soviet coins.
On the obverse,
1) The angel is somewhat similar but different
2) The building on the right seems to be incomplete
3) The theme of the supposely commemorative ruble is similar as you have similar text.
With all these points to be considered, this is some sort of trial coin or some ridicious fantasy made up?!?!?!?!
3rd question: 1730 Anna ruble counterstruck / overstruck on what?!?!?!?
As you can see this Anna ruble was double struck, possibly done by another drunk mintmaster on vodka. But you should note of the ridiciousness of this poor Anna ruble.
As you can see, a ball was counterstruck on her mouth, as if it seems to make her want to shut up or she was too ugly. However, do take a look at the red line, it seems to be very confusing. There is another layer underneath this coin which I quite haven't quite fill the lines in... because of the level of ridicious difficulty...
If you have any idea what the underlying image could be, feel free to add in!
Sorry for these three questions - will wait in antipication what kind of answers will come!
