Thom Yorke did this when I saw him live in Oakland. All tickets had to be picked up at the Will Call counter, showing an ID. Then you could only go into the venue to the ticket check from Will Call (there were temporary barriers guiding the crowd). On the other hand, I had an extra ticket. I did manage to sell it for face value by organizing the deal just as I approached the pickup counter (someone else knew how to play the game), and we did a quick cash transaction for face value.
