What would a Musterbrand Wild Hunt Jacket fetch these days?

Sorry if it's not exactly the right place to post it but didn't know where else to post and it is after all Witcher related.

For those who don't know, over a decade ago around the time of Witcher 3's release, Musterbrand had a collection of Witcher related apparel and this Jacket was among them, with only 300 produced.

musterbrand — We are pleased to announce the Wild Hunt leather...

I bought one back in the day but have rarely worn it, not even 20 times as I'd put on a lot of weight during falls and winters and not fit in it and only lose the weight during summers when I'd not exactly be wearing a leather jacket. I'm trying my best to be able to lose enough weight to wear it this fall/winter but if I can't, I'd be interested in selling it so want to get an idea if I can.

BTW, for anyone who liked the jacket, while trying to find anyone selling it to get an idea on how much it is worth, I've seen numerous sites that sell leather (and some faux leather) jackets of the exact same design for a fraction of the price that I bought this so you can easily get this cool witcher related gear even if not the official one.
