Grader Premiums

What a CGC, BGS, SGC or other company's slab of a Garbage Pail Kids card sells for, next to the same card at the same grade in a PSA holder. Every number comes from real sales of the same card on both sides. Across every grader, a non-PSA slab has sold for about 70% of the PSA price (based on 962 sales).

How to read it

60% means that grade sells for about 60% of what the same card brings in a PSA holder at the same grade: a CGC 9 against a PSA 9. Above 100% means it sells for more.

A .5 grade is compared to the middle of the PSA grade below and above it. The top labels (CGC Pristine, BGS Black Label, SGC and TAG Pristine) are compared to a PSA 10.

measured rows have 5 or more sales of their own. pooled rows have fewer, so their number leans on that grader's other grades. They are an estimate, not a market rate.

How we work it out

  1. We take sales of non-PSA slabs of GPK cards (from Card Hedger and eBay sales we tracked ourselves). A sale counts only when we could prove which card it was (year, set, card number, a/b, variety) and the grade in the listing matches. Lots, reprints, qualifiers and cracked slabs are left out. Doubtful ones wait for a person to check them.
  2. For each sale we find the same card in a PSA holder at the same grade and take the middle of its PSA sales within three months either side.
  3. The non-PSA price divided by that PSA price is one ratio. The number shown is the middle of those ratios, steadied toward the grader's overall number when a grade has only a few sales.
  4. Likely range is where the middle number would land 9 times in 10 if we had a different set of cards. Wide means few or scattered sales.
  5. Graders with no GPK sales yet (TAG, Arena Club and others) show the all-grader number until their own sales arrive.

We test this every night on sales the numbers never saw. These percentages, applied to the PSA price, miss the next non-PSA sale by a typical 35% (1105 sales tested). Single sales of a card swing that much on their own, so read these as a guide, not a quote.

Rebuilt nightly. Last worked out 2026-10-09. 962 paired sales behind this page. These are observed sale ratios, not an opinion about which company grades harder. Not financial advice.
