You can't compare books like that. Especially in this market. They have different supply and buy-in points. Not everyone can afford a high end superhero key. Ant Man was pretty much announced at SDCC in 2006 (wow, doesn't seem like it was that long ago). But, was not put into full production until around 2013-14. That's really when people start to notice because it's "real" at that point.
In 2012 TTA #27 was a $7,800 in 8.0 (i just picked what I felt was a decent high end buy-in grade). 2013 it went to over $10k with one sale. 2019 it's around $17,600. 225% increase roughly.
In 2012 MP #47 was $112.50 in 9.8. 2013 it quadrupled. 2019 it's sitting around $560 or 500% increase.
