2017 MARKET UPDATE:
There is still support for this book in lots of grades. However, CGC 9.8s are pretty easy to come by, and prices have stabilized.
We still think this book has potential, and it's a cheap risk even if it continues its downturn.
Already the subject of a short film and now an NBC TV series in the works, Hellblazer is hot property. However, the first Hellblazer comic book is not valuable and has in fact dropped in value.
This is the first true appearance of John Constantine. True speculators have piled into early 'tryout' or cameo appearances elsewhere, but the weight of money is behind Swamp Thing #37, and so should yours be.
Stick to a white pages CGC 9.8. There is nothing else worth buying.
The kind of book you might find at a garage sale for $2, mind, so a cheap copy in any grade is a good find.
