2018 MARKET UPDATE: INFINITY WAR IS ALMOST UPON US
The new Avengers: Infinity War movie has rekindled interest in this comic book, but all the excitement is already priced into most of the grades.
Thanos clearly has a big future in the MCU, so this book still has upside.
Recent sales in grades below 9.8 still indicate this is a hot book still, but you may already have left it too late to take a profit at the highest grade level.
Prices are stronger than a year ago by about 10 to 15 percent.
2017 MARKET UPDATE:
This book is too common to sustain its price rises, with plenty of supply soaking up the demand, and a general feeling that Thanos might not be the big thing everybody thought it would be.
CGC 9.8s have softened, but other grades have still seen some increases. Perhaps the 9.8 price above $5K was too much for average buyers. One to keep a close eye on, but if you're planning to invest you should proceed with caution.
Thanos has gained huge importance in the Marvel Universe.
In addition to making an appearance in the Guardians of the Galaxy movie, and a couple of cameos in the various cut-scenes of Avengers movies, Thanos will be integral to the upcoming Avengers: Infinity War movies.
Prices on this book have taken a pause for breath, but we see a lot of upside still. CGC 9.4s are selling for around 50 percent more than two years ago. 9.6s are about 35 percent ahead of their 2014 average.
It's a pretty common book in grades lower than 9.4, and we recommend you avoid those lower grades if you're looking for good ROI.
