How accurate is The Chip Rack for chips? The Overstreet Comic Book Guide is just that, a guide. The price of chips and comics depends on the ever changing market. If they find a box of mint Superman #1's (highly unlikely) the price would go down.

Unlike the current chip market, comics have been graded and slabbed. Heritage Auction Galleries and other Auction Houses sell a lot of graded coins and comics for record prices (many times higher that guide value). It truly amazes me what something encased and graded does to an item.
