Featuring Marvel Comics #1, Amazing Fantasy #15, Sensation Comics #1 and MORE… Heritage Auctions is having one humdinger of a comic-book auction, featuring some of the most sought-after issues ever — including Detective Comics #27. “Detective Comics #27 (DC, 1939) CGC FN 6.0 Off-white to white pages,” reads the official description. “Not only is it in contention with Action Comics #1 as the most important Golden Age comic of all, it’s just about as hard to find in any grade! We’ve offered just four copies in higher grades in the last 22 years, and just two nicer copies in the past 10 years! But who could blame collectors for hoarding their copies! Herein are the first appearances of Batman (Bruce Wayne) and Commissioner James ‘Jim’ Gordon. The combination of desirability and rarity makes this issue perpetually outperforming its Overstreet value. Look for this to be the most valuable book in our auction! Batman co-creator Bob Kane did the cover and contributed interior story art, along with Joe Shuster and Fred Guardineer. Currently #2 on Overstreet’s list of Top 100 Golden Age Comics. CGC notes, ‘To my friend Bob Crestohl — Bob Kane’ written on page 1 in pen. Overstreet 2022 FN 6.0 value = $816,000. CGC census 3/23: 2 in 6.0, 14 higher.” The issue is sitting at $612,500, as of this writing, but it’s expected to go for about $1.5 million when the auction wraps at the end of the month, coinciding with the March 30 anniversary of Batman’s 1939 debut. That’s plenty cool enough, but we picked out a total of 13 comics from the auction to show off to you.
