I can't comment on most things for sure, but I wouldn't expect much if anything from the non-q9 items. Maybe you could get a bit for the zodiac.
As for the q8 axe, there are a few people who collect naked items (no inherent), I would wait until one of them sees this, but for a max damage q8 naked item they might give something.
Id merch the items from zodiac and below the zod maybe 20-30e,not sure how valuable the q10 is the q8 naked is whatever the collector pays for it,so dont be greedy.
