last month with a $1 million sale of Action Comics #1 (the first appearance of Superman) announced today that it has sold a higher-graded copy for $1.5 million.
Last month's copy was graded 8.0 (Very Fine) by Comics Guaranty; this copy was graded 8.5 (VF+). That's an incredibly subtle difference in condition, one most civilians (and many people in the business!) wouldn't be able to see. According to the CGC Census, this copy is the highest rated unrestored copy of the book in existence; there is a restored 9.0, but many collectors do not find restored copies as desirable.
This beats the $1,075,500 record set a little over one month ago (and only three days after the first Action #1 sale) by Heritage Comic Auctions for an 8.0 copy of Detective Comics #27, the first appearance of Batman.
While The Comics Chronicles is not an aftermarket site (although John is an Overstreet advisor), these moments are notable reminders of how the comics of the past continue to attract interest in the present. We are talking, again, of an appreciation rate of more than 1 billion percent over cover price. Not many collectibles have that kind of return on investment after 70 years!
