Tibet 1 Tangka

Hello

Please help me !
What year is this coin ?

Weight: 4.6 g
Diameter: 27 mm
Thickness: 1.10 mm



Thank you and Best Regards Levi

One way of classifying Tangka coins is as per the article "The Gaden Tangka of Tibet" by N. G. Rhodes which is available at http://www.onsnumis.org/articles to download.

zeno.ru also uses the same classification. Refer here.

Referring this classification and based on the symbols on the coin, I think this coin is of type F (x) and the period of this coin is between 1918-1922, similar to the one shown here.

Hope this helps.

Hello Parimal and thank you for your help.

I agree with you, this is the coin http://www.zeno.ru/showphoto.php?photo=49160 what you showed me.
But I have a question.

Why the KM number does not match.  
http://www.ngccoin.com/price-guide/world/tibet-tangka-1-1/2-sho-y-e131-cuid-56142-duid-152125
The year is (ca.1899-1907)   

Can you help me with the KM number please   

The KM number at the http://www.zeno.ru/showphoto.php?photo=49160 is missing the type number and hence the confusion.  
The previous Y# 13.4 is now Y# E13.1 i.e of Type E, but your coin is of type F.

The KM number of your coin is Y# F13.4

Thanks again for your help Parimal

I have one more question and I hope to enlighten me.

My coin is different from the picture
why ?




Best regards Levi

The south most symbol that you have question about is not different. Its the symbol representing right-spiraling conch shell surrounded by 3 dots. It is just a minor variation in the way the symbol in drawn is these two coins. Until 1932 Tibet's coins were struck by hand in different mints, so such type of minor variations are possible if two different engravers draw the symbols.  

Thank you very much for your help Parimal
