2017 MARKET UPDATE:
Most grades have softened in price, and barring the odd "record for the grade", there isn't much to cheer here.
The Shazam! movie was cancelled too. Time to drop this from the Hot 100.
There was a feeding frenzy on this book the moment the Black Adam actor The Rock was announced as the antagonist in the Shazam! movie. Prices have been crazy ever since.
While Shazam! #1 was initially a big gainer, copies flooded the market, forcing prices even of nice 9.8s with white pages lower as more supply choked off the demand.
Shazam! #28 is a different proposition. Later in the run (never a very popular series), lower print run, consigned for many years to dealer dump bins, and therefore seldom found in high grade.
Look for a 9.6, or if you can afford one, a 9.8, and don't be surprised if you can pick up copies at garage sales. Shazam! #28 just doesn't stick out the way a Detective #27 or Action #1 does.
