If you're asking about the moral dilemma of selling to a possible counterfeit then I'd say that it seems there is no real definitive proof or close to, so I'd probably make the deal (so long as you agree with his offer).
If it's about the price/value of this card then I haven't a clue.
If I had very strong evidence that supports that someone is counterfeiting cards, then I probably would NOT sell them anything.
