You got a hapster, which is an awesome cap.  I'm jealous of it.  I know there are plenty of people who would pay decently for one.
And I actually really like that shift key that has the black of the first shot showing.  If it's usable, that would be a really cool cap to have fun with.
Edit:  Looking closer, you should be able to get your money back if you want by selling stuff off.  You have a ton of set specific geek hack caps which always go quickly, a union jack cap I've never seen before, and a bunch of interesting little things you could sell.
