But what do I do with it

I got an amazing prize at an EDH tournament today.

An uncut sheet of the rares and mythic rares from Amonkhet.

Now, it's super sweet. I see lots of stores with uncut foil sheets as decorations but... I'm not one for decorating. So I guess I sell this to someone? But looking online it's not something that a price comes up for easily.

When I got it, everyone in the store went "Ooh!" and I just kind of was, well I was blown away because it is awesome, but even as a good problem to have, it is now mine to deal with. I mean, the store wasn't giving it away just because it's awesome. They had it as part of the prize pool for the tournament for a reason, right?

I kind of feel like a dick.

I mean, I'm trying to resolve getting a cool prize here that I can't really use and am unsure of how to go about selling it. It's like winning a car. Yeah, that's great, but what do I do now? I don't need a second car and it's not better than the car I have so I just deal with it?

It's challenging to be gracious and at the same time wonder about how something will impact you. I mean, it's not a big deal, I'm sure. I find a buyer for this. And I feel so lucky to win this rahter than getting the booby prize. But what do I do with it?

I'm so happy yet so confused.
