Until 1913 Tibet belonged to Chinese Empire. At 1913 Tibet became an independent country (de-facto), but at the same time any of states didn't recognize the independence of Tibet (de-jure). Anyway, Tibet was an independent country since 1913 until 1951 in fact. And had an own ruler (Dalai Lama) and currency. Monetary system of Tibet was quite difficult: 15 skar = 1-1/2 sho; 1-1/2 sho = 1 tangka; 10 sho = 1 srang.
In October 1950 Chinese army intured in East Tibet. The army of Tibet lost 5738 people and was defeated. At May 1951 Tibet became an autonomous part of the People's Republic of China. The last coins of Tibet was released at 1953.

I'm not going to start a debate of Tibet and China relationship but they do have some going back in 1600s. http://ykleungn.tripod.com/tibcoins.htm https://en.wikipedia.org/wiki/Historical_money_of_Tibet I have been trying to get my hands on a Qing dynasty Tibetan coin but found it just a bit out of my reach every time I see one for sale.
Now that's strange. Only posted part of my response. Anyway...I appreciate you posting the interesting coins from your collection, my friend. Bruce
