Bogus

In reporting a trial at law The Boston Courier in 1857 gave the following authoritative origin:--“The word Bogus is a corruption of the name of one Borghese, a very corrupt individual, who twenty years ago or more did a tremendous busine in the way of supplying the great west, and portions of the south-west, with counterfeit bills and bills on fictitious banks. The western people fell into the habit of shortening the name of Borghese to that of Bogus , and his bills, as well as all others of like character, were universally styled by them ‘bogus currency.’” So that the word is really American.
