will the book continue to go up? , sure... will it get to TOS39 or JIM83 $$ level. , IMO/ , No, not unless the movie is a HUGE blockbuster, and even then, not so sure
The book is certainly in the up and up without a movie, but with an announcement of one, I think it can go higher. It may reach the TOS 39/JIM 83 levels (they started off as "B" heroes before all the movies and now they are in the "A" realm). I can see it happening with Dr. Strange as well. Yes, the movie would have to be a hit for it to happen, but seeing how good the Marvel movies are as of late, I have no doubts about it.
^ Agree, ST110 has always been scarce to find. I finally found a high grade one after looking for a year. These prices are cheap come next year.
