Gentleman, need some advice: recently I obtained a brand new, made for me, Elvira Zippo. This one is unique. It has Elvira's portrait on BOTH sides of the matte white lighter, and regretfully I need to sell it. You may know the Elvira lighters are are and in great demand, especially the white background one. Since I need the cash, I'm wondering how much to charge? Easily $50, but how much beyond that? $70? More?
