Why this card matters
pop
PSA 10 commands an 8.6× premium over raw and listings sit at a moderate 142, but CGC 10 comps (n=5) at $105 vs PSA 10 at $258 signals grader disparity rather than pure supply tightness.
demand
Koffing carries light Gen-1 nostalgia but lacks the breakout character pull of a Pikachu or Charizard, keeping collector demand solidly mid-tier.
artist
Cosmic Eclipse secret-rare treatment delivers a striking full-art illustration that elevates this well above a standard Koffing print and drives aesthetic desirability.
catalyst
8.7% 30-day momentum is mildly positive but PSA 9 comps (n=5) at $51 and a single ACE 10 sale (n=1) at $166 make the trend fragile and insufficiently broad to confirm a durable breakout.
