Help for classification of Tibetan silvers

[AndP36]

Hi collectors,
my name is Andrea, I'm from Italy and this is my first message in this forum.
I'm basically a collector of world coins from XX century and I have these two Tibetan tangkas and I would ask your help, first of all to confirm that they are genuine and not counterfeited, and then to give a correct classification to them, considering that some varieties of this tipology exist.
The first one has a diameter of mm. 28 and a weight of gr. 5,2; the second one has a diameter of mm. 26 and a weight of gr. 4,2.
Thanks in advance to anyone who will bring his opinion in my topic.

Normal coins.
1. Ga-den Tangka, type D (ii), (1896-99), Mint: presumably Dod-pal, KM Y#D13.2, silver.
2. Ga-den Tangka, type F (x), (1918-1922), Mint: Do-de, KM Y#F13.4 (var.), billon.

Thanks very much Gusev for your kind reply and for these precious infos.
I would take advantage of your knowledge about these coins, to show you an other pice that I identified as 1/2 rupee Y#2.
Its diameter is mm. 24 and its weight is gr. 5,7; but on the edge it exhibits some excrescences of metal that make me uncertain about is authenticity.
What can you say about it?

Looks ok to me. Probably it was hinged omce.

I fully agree with Afrasi, good coin.
At the edge looks like remnants of solder.

"omce"
once !!!

I tried to be earlier than you.    So my fingers were too fast ... 

[AndP36]

It was a possibility that I didn't evaluate.
Thanks very much Afrasi and Gusev for your reply!

P.S. Just an other question about the 1/2 rupee: in what years was this issue minted?

OK.
According to Wang Chengzhi ("Sichuan Zang yang", "Tibetan Silver coins of Sichuan", China umismatics, 1983.3, p. 12-18 and plate 54) the Half Rupee coins were struck by the Chengdu mint in 1904, 1905, 1907 and 1912.

I reopen this old discussion to ask again your help for the correct classification of two more Tibetan coins: this time they are copper sho.
The first one has a diameter of mm. 24,05 and a weight of gr. 6,06; the second one has a diameter of mm. 24,10 and a weight of gr. 5,26.

KM Y#21.2, BE 15-57 (1923 AD) and BE 15-56 (1922 AD).
Lion look backwards and upwards.

[Gusev]

Weight varies 3.3-7.3.

  There's nothing like expertise to make coins come alive.

Thanks very much Gusev for your precious indications.
I take advantage of your great knowledge about this coinage to ask your help one more time for other two tangka.
The first one has a diameter of mm. 26,12 and a weight of gr. 4,94; the second one has a diameter of mm. 27,22 and a weight of gr. 4,49.
What are their correct classifications?
