Pc on assorted stuff

Generally people don't bother with PCing things like low end minis, low end weapons, greens, mods, because there is a special Kamadan Chat Log for it (https://kamadan.decltype.org/), where you can find all the mentions of a given item. Those logs don't specify a price, don't take a single post as a definite "Source of Wisdom". The site is here only to give you a remote idea about the item's value and find other players looking for something you are willing to sell, or if you want to find someone selling certain item.

Overall don't bother collecting non-maxed mods, since they don't hold any value (perhaps with an exception of "Forget me not" 19%, being a cheaper alternative to it's max version, which goes for 20-40e). The mods usually go for 1-5e, depending on demand.

Totem Axe might be worth a couple of ectos, if you find someone after it. Usually, only the greens with either green-exclusive skins, or very useful mods are worth "something". The others serve as hero weapons, since people don't have to bother with modding gold/blue weapons. Also you should check out Legacy's "Buy" section. There is several green collectors out there that might lack the skin that you have, so go ahead and check their lists, perhaps you have it.

As for that "Earth Wand - 20 HCT 19 HSR", if it's an oldschool (unmoddable/dropped in factions/prop) it might be worth a bit, I'm not a caster weapon guy to PC it though. However if it's insc., the skin itself is worthless, so just salvage off that 20HCT mod out of it.
