Weighting every grade by how often this card actually comes back at it, a submission is worth $24.44 on average. The card plus the $25 fee costs $26.74, so grading loses $2.30 on an average submission. Only 29.5% 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 Koga's Ekans on this page is the 1st Edition printing from Gym Challenge, and it trades at $3.40 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 $44.00. 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.
