Depends on the stats and lvl; lv29 Leather "Of the monkey" gear will fetch 10-20g easily for twinks; 30-39ish of the same gear might catch 5-6g, cuz monkey's still a very popular mod for rogues and pre-mail hunters; same with Eagle/Bear mail for Palas/Warrs respectively(though this is on Mag's economy which since BC has gotten a little odd, lv12-30 cloth gear tends to run 3g minimum lol); just try to search for similar lvl or named items, DE/vendor all "Boar" and "Whale" gear(Spirit is only useful on Cloth with Int for priests, noone else wants it; Str is only good for warrs palas and feral druids for shield block and ap respectively); just use yer judgement and check for similar stuff ;p If anything sells for 2-3g, vendor it instead of DEing, better to save up for the epic mounts than "hope" youget good DE mats or lvl useless enchanting too much too soon
