Type a number, or pick an example, and read the ledger.
Labelled sample data, not live results. Everything this page shows
comes from a small fixed set of worked examples, written to fix the design of each state.
Nothing here queries eBay or a grader. The live tool screens a number two ways: against
that grader's cert-number format, and against SlabEye's sweep index of graded-card
listings. It reads a grader's own record for one grader only — PSA, through PSA's
API trial — and prints an honest “not readable” row for the other nine.
Worked examples — one per state:
The result ledger
Every state the ledger can print
The vocabulary is fixed. SlabEye reports what it observed against the
sighting graph and, for PSA, the record it read; it never states that a card is or is not
what the label says, because it cannot see inside a holder. A screening result carries
one of four verdicts — 01 to 04 below, and those four are the whole set. The last
two blocks are marked plainly: they are designed states the live screening result does not
emit, and each says why. Every block is rendered by the same code the lookup above uses,
from the same sample data.
How to read a verdict
What each state does and doesn't say
Green is the absence of an observed conflict.Not a statement about the object in the holder. Two copies of the same print look
identical to any screen, which is why the ceiling line rides on every green verdict and
cannot be dismissed.
Caution is a prompt, never an accusation.“Seen on other live listings” fires as soon as the number is on
one active listing in our last sweep — a slab is a single physical item, so
the commonest reading is that the listing is the seller's own. The verdict describes
listings, never sellers.
The second caution is about seller accounts, not listings.“Listed under multiple seller accounts” fires when the number's past
listings span more than one account and none is live. Ordinary resale looks exactly like
this, which is why it is context and never a stop.
The format state stops before any lookup.A number that fits no shape the grader issues is usually a typo or the wrong grader
selected. Nothing is screened, and no record link is offered, because there is no number
worth looking up yet.
The last two states are not screening verdicts.“Resolves to a different card” belongs to SlabEye's listing review, not
to a number you type; “flagged by a report” has no report corpus behind it at
all. Both are rendered here so the design is settled, and both say so on the block.
Data slots are honest or empty. The ledger only ever shows what
SlabEye actually holds: the format check, the sighting counts, and — for PSA only
— the record read live from PSA's API and not stored. Population, sub-grades and a
reference image are designed slots that no readable record fills today, so the ledger
prints the not-available row instead of a plausible-looking number.
Questions
About this page
Are these real listings?
No. Every cert number, count, seller handle and date on this page is sample
data written to show how a state reads — none of these numbers is in SlabEye's
index. The live tool screens against a daily sweep of graded-card listings on eBay US,
UK, Germany and Australia; this page queries nothing.
What happens if I type a number that isn't an example?
You get a neutral result saying so, plus a working link to that grader's own
record page. A demo that returned a clean verdict for a number it never checked would be
the one dishonest thing this page could do, so it doesn't. The format check is real
either way: it runs against the same per-grader shapes the live tool uses, on the number
exactly as you typed it.
Is SlabEye telling me a card is what the label says?
No, and it cannot. It reports discrepancies it observed within its coverage.
A clear screen is the absence of observed conflicts, not a verdict on the object inside
the holder. The grader's own record is always one tap away.
