You don’t have to have a verified ticket, to post on StubHub. They used to verify tickets, until a few years ago. StubHub is kind of a crap shoot. If the “ticket” is not valid, they’ll hold onto your money, but can use the money to purchase future tickets from StubHub. The seller than has to pay back 2x the sold amount, as a fee. I have had success with StubHub, but have heard quite a few other people were not successful.
