the ones with a non-lit candle go for more. one like this recently sold for 150mil, i think that was a bit high tho.
another one sold recently for 35mil, i forget if it was lit or unlit. Even lit that was probably on the low end.
Question tho which might help you out as well. I found an unlit skull with candle a while back, and display it unlit, but does anyone know if the unlit ones can be lit? and if lit can they be shut off again? Ive wanted to try lighting it but dont want it to get stuck that way and am too afraid to try. So unless someone here can confirm one way or the other, Brockis i wouldnt suggest trying to light it if it is unlit.
