What do you think of

falsification, counterfeit, hoax, fake, forgery, fraud, sham, imitation, leg-pull (I'm sure there's more)

?

What we have in Russian:
Фальсификация, подделка, подлог, имитация, мистификация, обман (but is more general "cheating", so I didn't include English "deception", "swindle", Russian "мошенничество" and other words ).

To tell you the truth, I can feel the difference more or less, the only thing I don't know, why there should be "hoax" when there are "fake" and "forgery" or "practical joke".
