Best case only — no gem-rate evidence 1

Fewer than 10 graded copies in the PSA and CGC population reports. They clear the grading cost if they gem — that is all the numbers support.

Psyduck cards that clear the grading cost at PSA 10 but have no measurable gem rate

#	Card	Raw	PSA 9	PSA 10	Cost	Best case	Gem rate	Expected	Sample
24	Psyduck δHolon Phantoms #81 · Classic (2004–2010)	$18	—	$6,500	$684	+$5,798	—	—	none <10

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 2026-08-26). 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.
