When we reported the record $1 million paid for Action Comics #1 on Monday (see “The Million Dollar Comic”), we noted that another key auction was also underway.  And in the second record sale of a key high quality Golden Age book this week, a CGC 8.0 copy of Detective Comics #27, the first appearance of Batman, sold for $1,075,500 (including Buyer’s Premium) in a Heritage auction that closed on Wednesday. 

The Detective Comics #27 was bought by a collector for $100 around 40 years ago, and kept, and preserved, until its sale this week.

That price gives Batman a slight lead over Superman in the 8.0 copy first appearance price derby.  Both prices were roughly triple the previous record price paid for a comic.
