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.
Question is, is Dr Strange even at the level of Iron Man/Thor before their movies? .. i don't think so..
will ST110 go up in value as it nears "movie time" , yes, without question. will it get to the level of TOS/JIM. Id be really hard press to think so... (if not flat out , no) but thats my , stranger things have happened!
It's all speculation and guesses at this point. No one really knows for sure what's gonna happen in the future. All we know is that the book was undervalued for all these years and finally it is getting the respect and attention it deserves.
