Trade and deception are different activities, and calling one the other does not merge them. A hustle means finding something people want and getting it to them; selling a copy as the original means taking the price of a real thing and delivering something else. One person ends up with the money and the other has been had.

Describe what you are selling exactly, including the flaw and the provenance you are not sure about. You will get less for it and you will keep every buyer. A name that holds up is the only inventory you can sell twice.
