Tibetan Coin

Hello!  I have what I believe to be a Tibetan coin.  I don't know how to date the coin, or determine its facial value.  I've attached a picture below.  




Can anyone help me identify this coin?

   Looks a bit like this one. Welcome to the site.  

One of our members has a site with many calendar converters. Here is Tibet one ...

I was just replying and you got there first! I think it is this one? 1 Sho.

And indeed, Welcome.

Thank you both!  That does look right.  The date converter was very helpful as well.

I think I have a 15 (1924) 58 1 Sho, with dots.  I think :)

 Just agreeing with date - the 58th year of 15th cycle - 15/58 = 1924 like you said.
I made an image as well, in case anyone wonders how it is calculated. Hope it is right what I found.
