I guess I can provide an "outside" perspective with virtually no experience.
I decided to collect the Star Wars original 107 issues + annuals last November after being a Star Wars collector for the last 25+ years. I read comics on and off but never really considered collecting them prior to late last year.
In reality, most of the original series of collectibles around Star Wars are priced beyond belief. Try and collect the original set of action figures and the money is crazy.
When I started looking around for a possible collectible that was around the original series, that I could still afford, I found the comic run actually pretty reasonable in comparison.
When I first started looking in November, I found #1 9.8 at about $700. When I checked "gocollect" I noticed the book had been rising from about $500 to about $700 in past few months. I hesitated in buying #1 because I needed so many other issues and I could pick those up for $100 and below at 9.8 for the most part outside of a few keys. This is also started to change.
I followed the last 3 months of #1. It went from $700, $800, to $1000 in about 1-2 months. It held at $1000 for 30-45 days, then suddenly this auction popped at $1,700.
While matching, I noticed another dealer had listed qty 4 - #1 9.8 white pages at $1000. In the course of 5-6 days, it went to $1,100, $1,300, $1,500, and now he is asking $1,800 having sold one. This occurred over 5-6 days. He obviously was watching the same auction.
Side note, I was completely lucky, a good friend bought me a #1 9.8 white pages as a gift as he realized I had started collecting the series. Problem solved :-)
I guess my only point is, if the Star Wars collector crowd really shows up in force (no pun intended), I would expect this whole series to move. Star Wars people are truly "completest", so unlike the comic crowd that has moved to keys, I think Star Wars will be one of the few that still collect full runs.
The comics, in my opinion, have been one of the last "original series" collectibles to truly move. I think it will be driven by Star Wars people as much as comic people that jump in once they see the movement.
Lastly, "slabbing" has actually made it more attractive to Star Wars collectors IMO. People that have not been paying attention to the comics world (like myself), completely missed the graded - slabbing process that was created 10+ years ago.
I realize that is highly "debated" in the comics circles, but for Star Wars people, it takes away the grading process (that they have no clue about) and provides a product that "feels" like a true collectible in a case. It draws in a new crowd for comics for the more general collector.
It did for me.
So as complete outside novice (who is probably totally wrong!), I expect the entire run of Star Wars comics to move in high grade (especially 9.8), slabbed form as Disney continues to build this franchise over the next 10+ years. It will be in the parks, on the movies, etc. It will allow fathers to pass on their love the movies to their kids. It will continue to drive interest in the original series collectibles. It will allow many of us, I hope, to forget the prequels, and use this new wave to pass on our interests :-)
In fact, the mid-issues that have very low census numbers at 9.8 will get high money. Once you get a few Star Wars guys all trying to complete the best run, it does not matter to them if it is #1 or #28, they need it. I think this will surprise some comic people.
Just a theory from a non-comic guy!
