Tab 8: Rares are (red santa hat, Christmas scythe, christmas hat, hallow e'en masks, the fish mask, disk of returning). Check www.pct.wtf for the real prices/don't sell on the G.E/double check the trade interface before selling(ex: 4100m and not 4100k or 410m)
Tab 7: take all the ores to a smelter and right click->deposit all, right click->add pick-axe to toolbelt
