Did the plastic pay?

Looking up one slab, and whether grading it was worth it

Type the cert off a grading label. What that exact slab has done, what other copies at that grade sell for, what a raw copy sells for, and whether the difference covered the fee — at the $25 you probably paid and at today's $80.

  1. 01

    Type the cert

    The long number printed on the label. It is a serial number for one piece of plastic, which is why this lookup can answer a question no card-level tool can: not what cards like this are worth, but what this one has done.

  2. 02

    What this slab has done

    Every time it was vaulted, listed or sold on either chain, with the price and the date. Two copies of one card can trade months and hundreds of dollars apart, and this is the only place that difference is visible.

    Coverage is partial. Only slabs that have been vaulted and had their label re-read carry a record, so "nothing found" means we hold nothing on it — not that the grader does not know it.

  3. 03

    What the grade adds

    The median of other copies at the same grade, set against what a raw copy sells for. The difference is the slab premium — what the plastic is actually contributing today.

  4. 04

    Two verdicts, not one

    The premium is compared with the fee twice: at what you paid — the panel starts at $25, and you can type your own — and at today's $80. A slab that broke even at the old fee and would not at the new one is the ordinary case, and the honest sentence is that the waterline rose, not that somebody overpaid.

    Nothing here is a valuation. Every figure is a price a copy was listed or sold at on a date; the verdict is arithmetic over those prices and the fee you tell it.

  5. 05

    Save it

    A slab can be saved beside your cards. It stays in this browser, gets re-priced on every visit, and the report on your saved list counts it — how many are above water at each fee.

The break-even is the same sum either way round. For a raw card the tokenize page asks it forward — what would this have to come back worth — and this page asks it backward, on a slab that already exists.
