Some examples I have here: first is a silver yen, Meiji 38 (1905), second another of Taisho 3 (1914), both of which were bought from reputable Japanese dealers in the 1980s and are presumed genuine; the third is the forged Japanese trade dollar that I mentioned earlier - note the style of the Latin letters in particular, as they are what I term "Chinese style", which is something of a giveaway for forgeries. (Andy's 1914 forgery above has the thick, blobby, misaligned "Chinese style" Latin letters too.)
