Title: Tannu Tuva coinage 1934
Post by: gxseries on April 20, 2013, 02:48:57 AM
These coins seem to be hard to find. Much harder to assemble as a set. Fair enough, if you fork out hundreds of dollars, you'll definitely get nicer ones. Nevertheless, here's a couple of them.

If I am not wrong, these were struck in Leningrad. One year coinage. An interesting era of coinage where Tuva tried to declare independence and now is a part of the Russian Federation.

Much harder, or even impossible, is to find 1933. I have met only one image of such coin, but there must be all the denominations from that year.

I can do better. I have never seen a single type of Tannu Tuva :) Those coins certainly "lived in interesting times".

Never thought I would see a Tannu Tuva coin dated 1933 - believed they were only struck in 1934. That said, for 5 kopek coins struck in 1933 to 1935 - they are key dates that do cost a fair amount of money. Tannu Tuva coins happen to be struck in the same mint and same era. Makes you wonder if anything big happened back then.

Tuva coins are indeed hard to find. Not quite as difficult as Armavir coins, but close enough. That's a beautiful 1933 issue 'ciscoins'. I didn't realize they existed. In any case, here's one from my collection. 15 Kopejek.

This screwball alphabet, used for what appears to be Turkish send me to Wikipedia.   It was something invented in 1930, and eliminated in 1943.  They use Russian now, with 3 added letters.   Makes the coins that much more a window into a vanished time.

It might be good to post a pic of an aluminium 20 kopeek piece from 1934. Offered on ebay for some time now.

Hello
I'd like to know more about weights of those coins because I got a 5K with a weight of 4.77g and I saw one actually to sold on Ebay with a weight of 5.03g (Krause don't give weights of those coins).
My coin seems a genuine one but the surface is porous.
Is it a fake or the result of a chemical cleaning on a very used coin that could explain the difference of weight ?
Or maybe there is variations in weights of this issue : it would be nice if other members give here the weight of their coins.

Have you done a "ping test" on your coin?

Something else,
My coin got a medal alignment but on Numista it is wrote that this coin should got coin alignment
see here http://en.numista.com/catalogue/pieces27103.html
I am a little lost with this coin but as it was stroke in interesting time variations should be expected I guess

Hello,

I found here a table with the weight of Tannu Tuva coins

http://coinss.com/catalog_soviet/tuva_en.html (http://coinss.com/catalog_soviet/tuva_en.html)

Please note that the edge of 5 K. is here mentioned as reeded (as my coin) while Numista indicate a smooth edge, see here

Thank you

Hello
Zeno give the weight of 4.645 g for a 5 Kopekejek example here https://www.zeno.ru/showphoto.php?photo=174685 (https://www.zeno.ru/showphoto.php?photo=174685)

OK, I'll stick my neck out. I think the pinholes are cleaning, not casting, so the coin is genuine. Compare your coin with the others in the thread. All of them have oxidation. Clean it away and you'd see what you see on your coin: unevenly divided holes, concentrated in certain areas, absent in others. Nevertheless, the evidence is weak and there is a seat-of-the-pants element in my judgement, but unless you find differences in the design, I'll stick with that.

Don't worry much about the weight. This is close to emergency coinage in "interesting times". Even it they were minted in the best mint of the Russian Soviet Republic, sometimes, speed must have been more important than quality. Same thing for smooth and reeded edges. Some modern mint can still produce such errors even in peaceful times, while a forger has a vested interest in getting such a simple thing right.

Thank you Peter !

I also think that the coin is genuine (I found another one in better grade with the same cud errors)
That example was probably cleaned (with a chemical product or acid) after been damaged by environmental conditions

More pictures from my coin with better definition (previous was from seller)
And details of the cud errors on the other coin

It might be good to post a pic of an aluminium 20 kopeek piece from 1934. Offered on ebay for some time now.

More about this aluminium token compared side to side with the normal 20 kopeek coin.

The weight of the aluminium token is 1.42 grams and diameter is 24 mm with plain edge
Normal coin weights 3.45 grams for a 22 mm diameter with reeded edge
Both got a medal alignment
Please see pictures below

Strike details are similar to me but the token seems "uncirculated" (defaults are anterior to the strike) while the coin is worn with damages.
My guess is the token was an aluminium poor flan used to check the machinery before start the production of normal coins.

My coin weights 5,04 g, normative weight is 5 g like Soviet 5 Kopecks of the time. Edge is reeded, medal alignment. I requested a correction in Numista catalogue.
I believe that your coin is original, the deviation of weight could be explained by heavy corrosion.
