Run a free AMG cert lookup on any Audio Media Grading hologram number. AMG grades and encapsulates audio media, vinyl records, cassettes and CDs, and every graded item is tracked by a serial-numbered, tamper-evident hologram. Enter that number to check the record and see what is actually behind the slab: the artist, the album, the release details and the assigned grade, with high-resolution scans when the source returns them. Every check is screened against our Fraud Base of known fake, stolen, reused or compromised numbers, with 25+ authentication and grading providers supported in one place. CheckCOA is independent and not the official audiomediagrading site.
Checking more than AMG? CheckCOA also verifies PSA, Beckett BGS, CGC, SGC, TAG and 20+ more grading and authentication providers in one place.
Enter the AMG serial number from the hologram on the slab. AMG numbers are digits only, normally 6 to 10 of them. You can also upload a photo of the label and let OCR read it.
AMG, short for Audio Media Grading, is a grading company for recorded music rather than cards or comics. It grades and encapsulates audio media, vinyl records, cassettes and CDs, in a protective slab so the item can be displayed and stored without handling it. If you have arrived here from a card or comic slab, this is the wrong lookup: AMG covers music formats. Collectors also know the company as amgrading, the handle it uses across social platforms, and audiomediagrading is the full name it trades under.
AMG's approach to security is layered rather than single-point. Every graded item carries a proprietary, tamper-evident, serial-numbered hologram applied to the individual case. That same serial is recorded on the grade label and repeated on the Statement of Archival, the SOA document that accompanies the item. The point of putting the number in three places is that they have to agree with one another. A slab where the hologram, the label and the SOA all carry the same serial, and where the lookup returns the same record, is a much stronger position than any one of those signals alone.
Serial-numbered and tamper-evident, applied to the individual case. This is the number you enter.
Carries the same serial alongside the assigned grade inside the slab.
The SOA document issued with the item, showing the same serial again. Ask to see it on a resale.
This is where the check earns its keep. A registered AMG serial does not just come back as valid or invalid; the record identifies the specific release in the slab. Expect the artist, the album and the release information, together with the assigned grade, and high-resolution scans of the slab when the source provides them. That last part matters for buying at distance, because pressings of the same album differ and the scans let you compare the actual item against the listing photos rather than taking a seller's word for which pressing is inside.
Start with the number itself. AMG serials are digits only, so stray letters, spaces or a misread character from a photo are the usual cause, and holograms photograph badly under direct light. Beyond that, a recently graded item may not have propagated to the record source yet, and provider sources are not always available. A blank result is a reason to look again at the slab, not a verdict on it. If the number reads cleanly and still returns nothing, ask the seller for a straight-on photo of the hologram and the Statement of Archival together before you go further.
A standard grading lookup can confirm the record behind a serial. CheckCOA brings that into one workflow across providers and adds a safety layer: Fraud Alert checks against known fake labels, copied serials, reused numbers and compromised records.
Grading slabs attract the same tricks as every other collectible: a genuine serial copied into the wrong listing, a resealed case, a label that does not belong to the media inside. The three-way match between hologram, label and SOA is your best tool here, and CheckCOA screens every AMG lookup against a growing database of known fake, stolen, reused and compromised numbers on top of it.
A clean result is not a guarantee of authenticity. A real serial can be attached to the wrong item, and unreported misuse will not appear, so compare the record with the slab, the label and the SOA in front of you.
Use this AMG cert lookup on any slab carrying an Audio Media Grading hologram, especially when buying a graded record at distance where you cannot inspect the case yourself.
Enter the serial from the Audio Media Grading hologram and screen it with free Fraud Alert protection.
Read the serial from the hologram, then confirm the returned artist, album and grade match the slab label and the Statement of Archival that came with it.
Audio Media Grading. AMG grades and encapsulates recorded music, vinyl records, cassettes and CDs, rather than cards or comics. The company trades as audiomediagrading and is known as amgrading on social platforms. If your slab holds a card or a comic, you need a different lookup.
Audio media: vinyl records from singles to LPs, cassettes and CDs. Items are graded and sealed in a protective AMG slab designed for display and long-term storage, with the grade shown on the label inside the case.
On the serial-numbered hologram applied to the individual slab. The same serial is repeated on the grade label and on the Statement of Archival that accompanies the item, so all three should agree. Enter the digits exactly as printed.
The document AMG issues with a graded item, carrying the same serial as the hologram and the grade label. Together they give the slab several independent layers of security. On a resale, ask to see the SOA alongside a straight-on photo of the hologram, and check that the numbers match.
The record identifies the release inside the slab: the artist, the album and the release information, along with the grade AMG assigned. High-resolution scans of the slab are returned when the source provides them, which is particularly useful for confirming which pressing you are actually buying.
Yes. Checking an Audio Media Grading number on CheckCOA is free and needs no account, and every lookup includes a Fraud Alert check against known fake, stolen, reused and compromised numbers. A free account only adds History, Collections and Wishlist so your checks are saved.
AMG serials are digits only, so a stray letter, a space or a character misread from a photo is the usual cause, and holograms photograph poorly under direct light. A recently graded item may also not have reached the record source yet, and provider sources are not always available. Recheck the digits against a sharp photo before drawing any conclusion.
No. It confirms the serial has a record and what that record says. A genuine serial can be quoted in a listing for a different item, and a case can be opened and resealed. Compare the hologram, the grade label and the Statement of Archival against each other and against the returned record, and look for signs of tampering on the case.
No. CheckCOA is an independent verification tool. It checks provider records when available, keeps your checks across 25+ providers in one place, and adds Fraud Alert checks against known fake, stolen, reused or compromised numbers.
Yes. Every AMG Grading lookup is screened against CheckCOA's Fraud Alert database of 25,000+ known fake, stolen, reused and compromised certificate records. This helps flag known fake COAs, counterfeit slabs, reused serial numbers and other reported risk signals, but it does not replace expert authentication.
