The $1,075,500.00 USD copy of Detective Comics #27

Introduction of "Bat-Man" by "Rob't Kane"

Heritage Auctions is a gold mine for viewing rare-to-not-so-rare comic books. They auctioned this copy of Detective Comics in February 2010 and it brought in a considerable amount of money, a staggering figure well above the numbers that used to surprise (or shock) people back in the collecting days of the 1960s when anything over $100.00 seemed amazing.
