Russiancoin: you might get more responses next time if you start a new thread, rather than adding to an already existing one.

This coin is dated, according to the 60-year cyclical calendar used by the Empire, to 1905 AD. This one doesn't have a provincial mintmark; it was struck in the central mint in Beijing. It's listed in the Krause world coin catalogue as KM/Y# 10. In this condition, the value wd1040 quoted is about right.
Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis
