Suggestions getting bitcoin for concert tickets securely?

[Alt_Tbone]

I bought some concert tickets I can't use now and they were quite pricey.   I was considering trading them for their value in bitcoin but I don't know how I could ever do that securely. The other party would have to trust me to give them the tickets and I'm not even sure of the risks if I were to send them the tickets first.
Worse case scenario I guess they could stiff me and resell them to some unsuspecting third party?
Can anyone think of a way to do this with minimal risk?
