WartortleGrading odds
PSA has graded 1,063 copies. Where they landed:
Why the verdict weights the odds
Only 23.6% of copies reach a 10, which is why the top price is the wrong number to plan around. Weighting each grade’s PSA price by these odds, a submission is worth $168.73£127€148.60 on average against $146.94£110.59€129.41 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That clears $21.79£16.40€19.19, so grading a clean copy is worth the wait.
What CGC copies sold for
Sold prices from listings that named the grader and the grade, not asking prices, and not a PSA figure converted across. A CGC 9 runs about 0.44x the PSA 9 on the cards where we hold both, but the spread is wide enough that it is only worth quoting where copies actually traded, which is what these are. The count beside each price is how many.
CGC 9 and 9.5 are one row on purpose. A CGC 9.5 sells for 3% more than a 9 across the corpus and is the cheaper of the two on nearly half of cards, so the market is not pricing them apart and splitting them here would invent a distinction. BGS is left split because there the same test says a 9.5 really is worth about 30% more.
| Grade | Median sold | Sales |
|---|---|---|
| CGC 9 or 9.5 | $80.48£60.57€70.88 | 12 |
| CGC 8.5 | $27.65£20.81€24.35 | 6 |

The Onix on this page is the Normal printing from Southern Islands, and it trades at $59.79£45€52.66 in near mint condition. Only one printing of this card was produced, so there is no cheaper version to confuse it with.
Graded, it runs PSA 7 $50£37.63€44.03, PSA 8 $77£57.95€67.81, PSA 9 $100£75.26€88.07, CGC/BGS 9.5 $110£82.79€96.87, PSA 10 $445£334.93€391.90. PSA has graded 1,063 copies of it. 643 completed sales are on file.
What is a PSA 10 Onix worth?
A PSA 10 Onix from Southern Islands sells for $445. 25.6% of the copies PSA has graded came back a 10, so that price is the best case rather than the one a submission should expect.
Is Onix from Southern Islands worth grading?
On the numbers, yes. The average submission is worth $176.63 with every grade weighted by how often this card comes back at it, against $46.95 for a raw copy plus $99.99 to send it through PSA Regular, so it clears $29.69.
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 $445£334.93€391.90. 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.
