It is nice to walk into your local comic shop on a Wednesday and pick up your books. It is even nicer that by the end of the week some of those books sell for multiple times cover price. Batman The Shadow #5 Mattina Variant is one of those books.
Once the cheap copies were cleared out on eBay, they sold as high as $15.
Prices have settled a little, with listings anywhere from $5 to $15, why anyone would shoot for the low end to sell when the median sale price is between $8 to $10.
