I consistently searched the same terms in EQOA’s auctions. I did the standard buy low, sell high. Here’s a list of what I can remember off the top of my head:
Centaur Lance, valued at around 2 million tunar on Hodstock.
Windblast armor – low level, yellow plate armor that could go for 1-2 million a piece.
Sandblast armor – similar to windblast
Dragon Eye – the level 50 blade would occasionally popup.
Shocking foil – Level 37 procing rapier, sold at around 50-100k at top value.
Sandmauler – high 20’s 2H Dragon Eye, could sell for a couple 100k.
Bloodstained armor – very rare red plate armor for 20s-30s.
Heartsblood aluminum alloy and black sapphires – look for the ones sold as normal gems.
Any robe but mainly the Seisen, CV, SM, and Spectre.
Food items like the pie or costumes.
Everquest Online Adventures 
Yes i remember when these items where uber until noob stick and robe crafting replaced the cool uber robes any1 remember Seisein Robe.
never had full set of windblast i don’t know if it was a full set.
the thing today with mmo’s is u level to fast and the low lvl stuff don’t matter anymore unlike old eqoa before boon and such i hope it goes back to that.
I remember always wanting a grimblade
