pc some necro items for me please

I don't have a necro, so I have no idea about this stuff. Any help is appreciated, no matter how much you need to ballpark it.

Ok, this isn't a necro item, but I'm still curious ....
4)

nobody ... please?

1st one is worthless IMO
2nd is worthless
3rd 5k max, maybe a touch more
water wand prolly around 5-10k

I've seen 5^50 wands with 9% goin for up to 20-30k... usually the 10% ones go for 100k unless I'm mistaken

That water wand is worth about ~40k, imo.

water wand 30-50k

Thanks so much guys.
