Price history and graded value
Grading odds
PSA has graded 81 copies. Where they landed:
1 of the 4 grades priced above had no sales at that grade, so the figure is modelled from the grades that did rather than observed.
Weighting every grade by how often this card actually comes back at it, a submission is worth $57.86 on average. The card plus the $25 fee costs $48.64, so grading clears its cost by $9.22. Only 55.6% of copies reach a 10, which is why the top price is the wrong number to plan around.

What moves the price of this card
The Koffing on this page is the Reverse Holofoil printing from Scarlet & Violet 151, and it trades at $0.27 in near mint condition. The other 1 printing of the same card sits lower, which is normal: the scarcer print run always carries the premium.
Condition does most of the work below the surface. A copy with soft corners or a print line off centre trades well under the market price shown here, and a copy clean enough to grade trades well above it, which is why the PSA 10 sits at $76.03. Before you value your own copy, look at the corners under a light and check the centring on the back, where most cards give themselves away.
