Once again, it's a TV series that is driving the value of a comic book. As the Walking Dead has proven, a common-as-dirt series of modern comic books can fetch serious money. Chew has the potential to match it.
Walking Dead #1 is also on the Hot 100 list.
Just to prove that supply and demand are not exclusively responsible for values, here is a modern book that is pretty common, yet prices are rising.
There are even a few CGC 9.9s and a 10.0 floating around out there, if you can find them.
Surprisingly a 9.9 is only about $1,000 at the time of writing, while a 9.8 is about $400. I'd push the boat out if you can afford it. (I doubt whether the 10.0 will come back to market anytime soon...)
