Gem rate is the share of PSA-graded copies that came back a 10. A rate off a handful of copies says more about who sent them in than about the card, so these two lists only count cards with at least 100 graded. The median Cloyster card on them gems at 15%.

A low population is not the same as a hard card. “Few sent in” means few copies have been graded at all, or they gem at a normal rate; “Hard to grade” means at least 100 have been graded and they come back a 10 at under half the median Cloyster rate.

Gem rate from 20 PSA-graded copies. 30d move is the PSA 10 price over 28 days. Premiums need both prices at $5 or more. 1st Edition and Shadowless printings are their own rows, with their own prices and PSA counts; PSA's sales record is kept per card, so they show no sales count.

Cite these figures

UltraBall tracks 14 Cloyster cards with a PSA 10 price, with a combined PSA 10 population of 210. Across the 4 Cloyster cards with at least 100 PSA-graded copies, the median gem rate is 15%. PSA's sales record shows 4 Cloyster PSA 10 sales worth $50,220 in the 90 days to Nov 11, 2026, across the 3 of those cards it has sales for.

Source: UltraBall, ultraball.com/pokemon/cloyster/psa-10, observed Nov 12, 2026. Sample: every English Cloyster card UltraBall tracks (14); populations from PSA's population report; sales from PSA's cert-linked sales record. Method below.

How these figures are made

Population: PSA's population report for each card, as PSA publishes it. Copies sent in, not copies in existence.
Gem rate: PSA 10s over every PSA-graded copy. Shown from 20 graded; ranked, and used in medians, from 100.
Prices: UltraBall's PSA 10, PSA 9 and raw near-mint prices, the same as each card page shows. A price leaves out sales far from the rest.
Sales: Cert-linked PSA 10 sales: each tied to one slab by its PSA certificate number, so a sale is this card at this grade. The record has sales for 3 of the 14 Cloyster cards; the rest show “–”, not zero. 30 and 90 days count back from the newest sale on the record.
Matching: Raw and graded figures are for the same card; a 1st Edition or Shadowless printing is kept apart from the Unlimited card.
Liquidity: PSA 10 sales in 30 days over live listings; days of supply is live listings over the average daily sales.
