2018 MARKET UPDATE:
Having dropped like a stone after the rather lame movie appearance, this book finally had to be removed from the Hot 100. There are just too many hotter books for it to keep its place.
Recent sales are cooling off further.
Deadshot was a surprise casting choice for the Suicide Squad movie. And yet it somehow worked. Half a year after the movie is out of theaters, we have a book that's still under-valued in most grades.
There are some pretty encouraging signs of price support. And come on, people, this is a book published in 1950. They are scarce.
Two words nobody really expected to be saying about movie madness: Suicide. Squad.
The most surprising of the DC movie announcements really took the back issue bins by storm.
Books like Brave and the Bold #25 (first Suicide Squad), Suicide Squad #1 from 1987 and all kinds of bizarre stuff with first appearances of Squad characters rocketed in value overnight, as speculators jumped on board.
Batman #59 is a bit of a different proposition, being a genuinely tough Golden Age book with only 86 unrestored examples in the CGC census. You may have to be less choosy about which copy you invest in.
