Sounds a bit high to me. I mean, from a collector perspective, who is making a collection, sure I could see it.
If a shop, friend, etc is selling it to you, cash, then I'd think twice.
Nightstalkers, I hope you are kidding.
The Dark Rituals are in horrible condition (i don't get that people would pay 17 bucks for them) and the pins.. well, that actually up to you!
