Question about this DBZ Box Set

Hi all. I picked up this DBZ box set at a consignment store for pretty cheap the other day. Does anyone know what it’s worth? I am a fan of DBZ but not much of a collector when it comes to manga.

I was going to post in /r/mangaswap but I don’t think they allow posts that aren’t buying/selling/trading and right now I’m just trying to figure out what it’s worth. Mods, let me know if this type of post isn’t allowed here.
