Coin identification

Hello and happy new year,

Please help me identify this coin from Tibet. This coin I can not find it in the catalogue, there are only 2 coins which are similar. I want to add it.

Here are some details: silver, 27 mm diameter, 3.4 grams, 1 mm thickness.

Attached some pictures.



Thank you

Your coin is of Type E(iii).

So it will be Y#E13.3 in the listing https://en.numista.com/catalogue/pieces18922.html

Thank you very much for your help.
