[Q] Head Warmer with the Burning Flames Effect

Hey, I've never been a trader but the pyro is my favorite class, so in honor of his new video I bought some burning keys for my burning boxes. In one of them I got a Head Warmer with the Burning Flames effect. I don't really know how I would go about trading this or selling it, but if its actually worth something it might be worth the effort.

If its about the same as any unusual ill just keep it and enjoy it whilst I burn things, however if anyone wants to make offers or pipe up, I like all things pyro. My specific thingy I want would be a strange postal pummeler.
