How to check a list of certs at once: the bulk check
A binder, a show case, a consignment or a vault list: paste the cert numbers, one a line, and read four flags for each before you open a single grader’s page. Up to 500 certs a run, free, no account.

The short answer
One slab at a time is the right pace for one slab. A binder of forty, a consignment of two hundred or a vault list of five hundred needs a first pass that narrows the list before anyone opens a grader’s page. The free bulk check at brich.house/check/bulk does that pass: paste the certs one a line with the grader before the number, or add a CSV with grader and cert columns, and read four flags for every row. Whether the number is in the grader’s usual shape. Whether the same cert turns up twice, in your list or on more than one vault token in the public platform index our watch reads. Whether the cert has an open report in the Brich House loss register. And a link to the grader’s own lookup for each one.
The list is read for the run and not kept. Brich House counts runs and flags, never the numbers checked or who checked them, and it never fetches a grader’s page for you: the link takes you there, and the grader’s record decides what it graded. A flag is a reason to look at that row first. It is not a finding about the card, and the card in hand decides the rest.
The list, step by step
- 01Write the list from the slabs, not the listing. Read each grader and cert number off the label in hand, or off your own record of the collection. A list copied from someone else’s spreadsheet carries their typing slips, and the format flag finds some of them.
- 02One cert a line, grader first. PSA 12345678, CGC 4012345001, SGC 1234567-001, TAG N1234567. Or a CSV with columns named grader and cert, in any order. Format the cert column as text first, so the spreadsheet keeps leading zeros and long numbers as written.
- 03Run the list. Press Check the list. Each row comes back with its four flags and a link to the grader’s own lookup. Download the CSV if the list is long; it carries the same columns and the date of the run.
- 04Start with the loss register. Any row with an open report in the Brich House loss register comes first. The flag shows the status and a reference, nothing about the owner or the loss. Stop on that row and ask the seller before anything moves.
- 05Then the same cert twice. A cloned flag means the number appears more than once in your list, or more than one vault token names it in the public platform index. Open both rows. A duplicate line in your own list is a typing slip; a cert on two tokens is a question for the platform.
- 06Then the formats. A number out of its grader’s usual shape is usually a dropped or doubled digit. Check it against the label and run that row again. A number that stays out of shape has no record to find.
- 07Open the grader’s page for the rows that matter. The link on each row goes to the grader’s own lookup. Match the player or character, the set and year, the card number and the grade, and the images where the grader shows them, to the slab in hand. The ten-second check, row by row.
- 08Keep the run with the collection. The downloaded CSV, dated, beside the photographs and the list. The next run, before a sale or after a move, is compared against it. Two dated runs are the start of the collection’s record.
What this check does not prove
- That a clean list is a clean collection. Four flags narrow the list. A row with no flag has a number in the usual shape, once in the list, with no open report. It says nothing yet about the card under the label.
- That the slab in hand is the one graded. The lookup checks a number. A label can be printed to copy a real one, so the card, the label and any images on the record have to match the slab in front of you.
- Who holds the card now. A cert records the card and the grade on the day it was graded. It says nothing about who has held the card since, or how it got to the seller.
- What the card is worth. A grade is not a price. The lookup says nothing about value, and neither does this guide.
- Ownership. A matching record does not show who owns the card or whether the seller can pass title to it. That is a question for the seller, in writing.
Questions
- How many certs can I check at once?
- Up to 500 a run, free, with no account. A longer list goes in two runs. Rows past the limit are counted as not checked, so split the list before you paste it.
- What does one line look like?
- The grader, a space and the number: PSA 12345678, CGC 4012345001, SGC 1234567-001, TAG N1234567. A grader’s own cert link works too. Bare numbers take the grader picked above the list, so a mixed list needs the grader on each line.
- What does the cloned flag mean?
- One slab carries one cert. The flag shows when the same cert appears more than once in your list, or when more than one vault token in the public platform index names it. A re-listed token or a typing slip can raise the same flag, so it is a reason to look, not a finding.
- Does the bulk check look the certs up on the graders’ sites?
- No. It builds the link to each grader’s own lookup and leaves the reading to you. Brich House has no affiliation with any grader, and each grader’s page is the record of what it graded.
- Is my list stored?
- No. The list is read for the run and not kept. Brich House counts runs and flags, never the numbers checked or who checked them. The CSV you download is made in your browser.
