selling copper ,or mining findingsFollow

You should be able to sell the copper bars semi-easily at the Auction House at the capital, Ironforge for Alliance or Orgimmar for Horde. The rough sharpening stones might be harder to sell since most people probably don't search for that. Try to save the stones and sell them in stacks of 20. Both blacksmiths and engineers can use the stones and might buy them. I can't really give you a price since it is usually different on each server. I would guess that you should be able to get about 30 to 60 silver for each stack of copper bars and maybe 20 to 30 silver for the rough stones. I hope this helps.
