I have over 500 and something coils and close to 40 brand new mods still in the plastic never opened. I figured that each box of coils for the cheap ones would be 3 to 5 dollars for the more expensive one’s 70 $10 into the most expensive ones $10-$15 for the line so I could go for a average of $20 a mod somewhere close to that but if somebody wanted to buy the whole lot I would let it go for 2500
