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.
