"If you have clear evidence that a buck-called coin was actualy historically used in reference to the skin of a whitetail deer-that it is only of USA origin, not of the other part of the British fur trading colony of the time, (where the much-fur-trading HBC was actually centered), why not put forward yourself (meself) for consideration?"

I have no such evidence, and I don't know what makes you suppose I would. Furthermore, I have no opinion to speak of on the matter; I'm just trying to get some clarification as to why it is seemingly 'apparent' that the term 'buck' was unknown in Canada before, I guess, the late 19th century, or maybe earlier 20th. Or later?

Oh, I just realized - my previous post was not in response to your (Ed T.'s) lengthy one; it was in response to an earlier one by Lighter. I should have made that clear - sorry!
