A Superbowl Stumper

Boruch: Hi, Shimon. I believe this is yours.
Shimon: My Superbowl ticket! Where was it? I was looking all over for it, and I missed the game!
Boruch: I felt that it wasn’t appropriate for someone of your stature to attend the game, so I took it.
Shimon: Wow! I really appreciate that you looked out for my ruchniyus, but please pay me $14,500 for the worthless ticket you stole from me and are now returning.
Boruch: Wait a minute! The face value of the ticket is $4,500. Where does $14,500 come from?
Shimon: That was the resale value of the ticket at the time you stole it from me. The Mishnah in Bava Kama says that the value of restitution is determined at the time of the theft. It is irrelevant what I paid for it or even if it was a gift.
Shimon: But why do I have to pay anything? I returned the ticket!
Boruch: Let’s say you stole a vase and cracked it. Can you return the worthless pieces and claim that’s restitution?! Certainly not. Here, too, this ticket is worthless. It’s like a broken vase.
