Not sure about ASM, but X-Men goes between $80-90 for CGC 9.8 . Depending on what you paid for it raw, but for a $30-40 book plus grading fees, (pressing fees?), minus eBay seller fees..you'd probably see $10 profit..maybe a little more..not really worth it in my opinion especially if you don't have a 9.8. On the other hand I do think the book has future potential and could see a price increase..so I would hold onto it longer. Personally I've been buying them here and there when I find them cheap and look 9.8 worthy.
