Yes there all Ga-den Tangkas and you must have the article by Nicholas Rhodes ( who sadly died last year ) from the Oriental Numismatic Society site to even start identification.
The hopeless KM standard catalog contribution serves more to confuse than enlighten, but remains a reasonable type and date system based on Rhodes. Scott Semans published a paper long ago but still available and quite useful if you can figure out how to convert to Rhodes index.
But the best online source of photos is the "britishmuseum.org/research/search_the_collection_database"
which has hundreds of photos.
You have the observe alignment correct but, despite the normal convention of simply flipping the coin, the reverse of Ga-den Tangkas are normally repositioned so that the 3 letter in the SW position of most of your photos is at top in the North position.
Your coins are F viii, C i, C ii, D ii, C ii, F viii, F vi/F vii, B iii(hook up), B iii(hookup, F xi, B i, F i, F iii, B ii, F x, B iii(hookup), B iv, F i, F xi at a quick glance.
All of these categories represent several dies, in some cases over 50 - you can see this by comparing your two F I coins etc. Or much more clearly on the BM site. You can date these by letter in KM (Krause).
They are all worth considerably over the scrap value of silver (though they have a vary variable silver content, later issues being bullion) .
in due time I ham hoping to extend the Rhodes index to cope with an individual die identification, but with well over 1000 it is a labour of love and a gordian knot.... so don't hold your breath
Am only occasional site visitor so please bear in mind
