People are just catching on to the fact this comic has a 3 page preview for Invincible in it. That makes this book potentially a key issue long term.
A lot of stores will still have this in their back issue boxes for $5-10, maybe even their $1-2 boxes if the condition wasn't great.
It has already jumped to $100 for a high grade copy and who knows where it will go long term as more people realize they need this book to complete their collection of Invincible Comics.
