PC on haloween?

This is more a question than a PC, just wondering if Haloween items are actually worth anythin now, I havent played the game for ages and i noticed them still sitting in my storage and wondered if they're of any use anymore.
Ty in advance

Nah keep them, I have brought 100 squash serums 175 each a few days ago. You might find someone willing to pay more but not much really.
