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 Iron Boulder card on them gems at 46%.

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 Iron Boulder rate.

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 6 of the 7 Iron Boulder 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.
