An email came though this afternoon announcing that a Superman #1 CGC 5.5 sold for $507,000 at ComicLink.
Superman #1 is such a crazy book. The print run for Superman #1 was what, 750,000? All those copies snapped up back in 1939 and in 2017 it's impossible to find in high grade. There are barely any pedigree copies and I only know of one copy that's probably above 9.0.
With Superman #1 5.5 is practically high grade.
Bonkers.
