PC needed on a couple golds

Could someone tell me if any of these have much value? I know not all the mods are perfect, but I have plenty of perfect mods to apply if it will increase the value.

1 2-3k
2 5-8k
3 mechant/salvage mods
4 merchant
5 8-10k
6 5-7k
7 merchant or a couple k (req too high)
8 not sure probably a few k
