First full Venom, a McFarlane cover, and a print run in the millions — so why does a graded 9.8 still command real money? The mechanics of a permanent key.
Amazing Spider-Man #300 (May 1988) breaks the usual rules. Keys are supposed to be scarce; #300 was printed in enormous numbers. And yet a graded 9.8 copy is one of the most reliable stores of value in modern comics. Why?
Because demand is not a fixed pie — it refills. Every new Spider-Man film, every Venom appearance, every kid who becomes a collector at 12 and a buyer at 30 adds demand for the exact same famous object. The cover helps: McFarlane's web-swinging Spidey in the black suit is arguably the most reproduced comic image of its era.
The discipline with #300 is condition and census. Thousands of 9.8s exist, so the book rewards patience: white pages, sharp corners, and — for the grail tier — a McFarlane signature or the newsstand edition. It is the centrepiece of our Venom shrine for a reason.
