Authenticate My Skeleton Zip-Up?

Is anyone able to authenticate this skeleton zip-up hoodie? I purchased it about a little under a year ago now and I want to know if it’s an actual piece of merchandise sold at tours or if it’s a replica. Is there any way to tell them apart?

I got this from somebody overseas who said they purchased it at a concert way back when and had it sitting in their closet for years.

Is anyone able to tell me how much this would sell for if it’s authentic and if it’s not, would it still be worth selling?

I’m considering selling it because I’m more in need of the funds than of this piece, even though I might end up reconsidering since it took me a year to even find this one.

It’s got a stain on the skull part and a bit of fading, but other than that, it’s in flawless condition.
