average submission value

Weighting every grade by how often this card actually comes back at it, a submission is worth $92.90 on average. The card plus the $25 fee costs $31.41, so grading clears its cost by $61.49. Only 1.2% 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 Dialga on this page is the Holofoil printing from Diamond and Pearl Promos, and it trades at $19.48 in near mint condition. Only one printing of this card was produced, so there is no cheaper version to confuse it with.

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 $1,848. 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.
