That's a very fast ascendance to the just-about-$50 club for Invincible Iron Man, the first appearance of the new Iron Man, Riri Williams, replacing Tony Stark in the suit and in the lead title.
That's the high raw price on eBay, though most are around $35. But in CGC 9.8 slabbed form, it's the second print that's getting the most attention hitting $130. The second print is far rarer than the first, though it can still be picked up for a lot less.
And issue 9 featuring a fuller appearance of the character has also seen a rise to $15 as standard.
There is of course more potential for growth if Riri Williams is cast in Iron Man 4. Or if Tomoe, an Inhuman who can control technology with her thoughts, becomes Riri's number one enemy as the Techno Golem… she was also introduced in Invincible Iron Man #7….
