mine drop prices
 

?????

Uhm... What?

should be in appraisal but i think he's talking bout the copper ore and stuff that's minable.

yep.
how much they sell for.
npc n vending
would people buy it if it was for vending?

People with the stone skill really need LQ copper ore. You can easily sell em for about 10c a pop, and they're pretty quick to mine. If you're level low 20s, it's a good way to crank out some coin
