Do you know how many New Mutants #98 I bought, and how long I held them, before they became "hot"?
Decades. And for decades, I took care of them, and waited while everyone laughed at the stupid purchase. And, while I didn't make as much as I could have, I can tell you that before 2014, I never paid more than $5 for a copy, and sold them all for north of $250. Each.
The key, as always, is patience. What comes around, goes around. Books that were popular in, oh, say 1985 might show a distinct probability in becoming popular again. Sure, a book like, say, Batman #376 will probably never become hot, because it never was.to begin with. But...a book like Tec #474, that enjoyed a bit of a renaissance in 2005...?
Now you're on to something. And it WAS highly sought after, for a brief time in 2005.
Then, a book like Batman #404....yes, I'll buy that every single time I pass by it for $1 or $2.
It has absolutely nothing....whatsoever...with knowing what character will "have a movie coming out." It has everything to do with understanding what drives the market, and how people react. And right now, they react to Detective #474.
A couple weeks ago, Bats #417 got the buzz. Next week, maybe Justice League #1 (1987) pops up.
Guess how many copies of THOSE books I have...?
