[DC Comics] Yesterday I found a Batarang on the ground on my way to work. How much does one of these things go for?

I figure there's got to be some collectors or something. Is it worth selling on ebay? Times are tough here in Gotham with bourgeoisie fat cats like Bruce Wayne getting all up in everyone's business. With Batman being so cool and such an inspiration, I almost feel bad wanting to sell it. But I need the cash.

Good luck selling it anywhere besides the black market if you want a good price. Everything left behind by Batman is considered evidence in the case against him since he's a vigilante. Anything that's found is seized by the Gotham City Police Department. 

I just wonder how large the evidence locker for Batman alone is.
