    This coin occurs in none of my catalogs.
    The size and some of the stylistic elements are similar to some of the 2 Paisa coins of Nepal from the 19th century.
    The obverse Chinese as I interpret it (I am not skilled in the language) gives the denomination as 10 wen. The top and bottom characters I take to mean "general circulation" or "convertable". Also I retired to my small library and found in one book on Yunnan coinage the tong yong phrase appearing on a small very crude lead (?) coin that was attributed to Tibet.
    On the reverse TBRL I translate as the "unified races of the [Chinese] republic". The center character fan could mean foreign, but I suspect it more likely is short for landsuccession which I believe is indicative of Tibet.
    The obverse Devanagari ("headless" ?) I am still struggling to understand.
    Any insights would be most appreciated.
Message from Stephen Tai (24-Jan-2000):
    The obverse legend Tong Yong Shi Wen is translated as 10 Cashes For Circulation.
    The reaverse legends is read as "Wu (5) Zu (Tribe) Gong (Together) He (Peace or Harmony), that mean "Five Tribes (Han, Manchurian, Mongolian, Islamic and Tibetian) come in peace". Fan is not necessary meant Foreign, in old Imperial Chinese vocabulary it also was used to stand for Barbarian, which could indicate the uncivilized minority or foreign people. In this coin, it should mean the former.
    I have seen this coin posted and discussed on a publication. Some numismatists consider it as a fantasy.
Message from Nicholas Rhodes (06-Mar-2001):
    This is a well-known Chinese fantasy, with one side copied from a Nepalese copper paisa of Surendra Vir Vikram (dating to c1787 saka = 1865 AD), but with additional Chinese characters. The coin was probably made in Shanghai or some such place in the 1920's or 1930's - maybe later - and has appeared in a few US auctions, if I remember correctly. Such fantasies were made only in small numbers, so it is not an easy piece to find, but has nothing to do with Tibetan currency, and I don't generally bother with such concoctions unless they "fall into my lap".
Any additional information highly appreciated.
