Expected = every grade outcome weighted by its share of the card's graded population, minus the raw price and the grading cost (PSA tier fee for the graded value plus ~$20 round-trip shipping, fees as of 2026-09-26). Best case is the PSA 10 leg alone. Gem rates come from a self-selected population — collectors grade their cleanest copies — so read them as an upper bound. Raw is a blended market price, not a sale of your copy. Full method and filters on the grading index.
PSA population 47
Every Dialga card with a PSA population reading, ranked five ways. A historical PSA 10 rate is the share of graded copies that came back a 10 — how hard a 10 has been to earn, not the chance your copy earns one — and it is only quoted on cards with at least 20 graded copies; the PSA 10 tables use the same floor. PSA counts as of 16 Oct 2026. How population is measured.

How to read the Dialga ranking
Every Dialga card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 31 Dialga printings pass. 31 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 26 of those keep a positive expected value once every grade outcome is weighted by how often the card actually receives it.
The order is expected profit, not the PSA 10 best case, which rewards the widest raw-to-gem gap whether the card gems one time in two or one in fifty. Here the top row, the Dialga-EX from Plasma Blast, gems 3.7% of the time across 1,042 graded copies: +$3,432 is what a long run of submissions would average, $73,776 is what one lucky copy returns.
The median gem rate across the sampled Dialga cards is 6.2%. Roughly one submitted copy in 16 came back PSA 10, and most rows here still cover raw price plus fee at PSA 9, so the PSA 9 price does most of the work. Of the 31 ranked cards, 19 still cover raw price plus fee at PSA 9, 12 need a 10 to break even and 4 lose money on expectation. 31 rest on a hundred or more graded copies.
Before you submit a Dialga card
Grading pays on condition. The four things every grader scores — centering, corners, edges and surface — can be checked at home before paying a fee, and a copy that is visibly off-centre or has a whitened corner will not gem whatever the population says. Those gem rates come from a self-selected population of clean copies, so a random copy does worse.
The cost column assumes a PSA submission at the tier covering the card's PSA 10 value, fees as of 2026-09-26, and raw is CardTrack's blended near-mint price, not a sale of your copy: pay more, or hold a lighter copy, and the break-even moves against you. Test a card with your own numbers in the ROI calculator, see the printings that fail the bar on the Dialga card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
Dialga grading questions
Which Dialga card is the best to grade?
On current numbers the Dialga-EX (Plasma Blast #99): 3.7% of 1,042 graded copies came back PSA 10, an expected profit of $3,432 per submission after the $3,799 grading cost, against a best case of $73,776 if it gems.
How many Dialga cards are worth grading?
26 keep a positive expected value after the fee, out of the 31 with a gem-rate sample of at least ten graded copies. 31 cards on this page have a PSA 10 price that beats the raw price by more than the grading fee.
What gem rate do Dialga cards get at PSA?
The median across the 31 sampled Dialga cards is 6.2%, so about one in 16 of the copies collectors chose to submit came back PSA 10. The strongest rate with a sample of thirty or more is the Origin Forme Dialga VSTAR (Crown Zenith Galarian Gallery #GG68) at 56.1% of 31,189.
Does the Dialga ranking apply to CGC or Beckett?
Not directly. The cost column is PSA's fee as of 2026-09-26 and the graded columns are PSA slab prices; the gem-rate sample falls back to CGC's population only when PSA has fewer than ten copies. A CGC or Beckett submission has its own fee and resale price.
