Are there any particular grades to aim for or is it not all that important?
um. highest grade possible without overpaying.
OK. So, say I want GL 7. We established earlier that raw prices for 6.0 are usually $100. Given the current boom in prices, what price would be overpaying for this grade?
price for a raw 6.0 is $100 ? No, what Gator said is that right now its around $100 a grade point, so $600 (he mentioned CGC graded copies also). Obviously the higher up you go the rarer the book gets as it is an early 60s DC and that formula probably stops working once you get to the 7.0 and up range.
Long term I dont think this book is a big enough key that in 6.0 it should be selling for that much but who knows, maybe the GL movie will just explode.
