Nice hook, but remember: the market’s a lot like a comic’s second‑hand price—full of surprises, not just spreadsheet numbers. I’ve seen “Freaks & Ghouls” from '92 turn up at auctions, and “The Badlands” by Mondo can skyrocket after a pop‑culture nod. Your model might catch a trend, but the real test is a quick grab at a crate at a convention and spotting a misprinted issue before anyone else does. Still, fire away—let’s see if your formulas can beat a seasoned eyesore‑hunter.
