Use this free MBA Grading cert lookup to verify an MBA serial number and pull the Report Card details for a slab. MBA Grading, short for Mike Baker Authenticated, grades raw cards, certifies collectibles and runs a Crossover Grading service for cards already slabbed by PSA, SGC or BVG, so an MBA record can sit alongside another grader's cert number on the same card. Enter the MBA serial number, or scan or photograph the slab label, and every check is screened against our Fraud Base of known fake, stolen, reused or compromised numbers, with 25+ grading and authentication providers supported in one place. CheckCOA is independent and not the official MBA site.
Checking more than MBA? CheckCOA also verifies PSA graded cards, Beckett BGS, SGC, CGC, TAG and 20+ more grading and authentication providers in one place.
Enter the MBA serial number from the slab label. MBA serials are numeric and typically 9 to 11 digits. You can scan the label with your camera, upload a photo or type the number in.
MBA Grading stands for Mike Baker Authenticated. It was founded by Mike Baker, who was the first employee at PSA and served as its Director of Grading for over a decade, and who has been grading cards since 1991. The company grades raw cards, issues MBA certification for collectibles, and runs a Crossover Grading service for cards that are already encapsulated by another grader. Each graded item gets an MBA serial number that you can verify here.
MBA publishes two things against a verified serial number. The Report Card carries the identifying details of the graded card and the MBA grade. The MBA Heat Map is MBA's transparency feature: it points out the key condition issue or issues behind the grade, so you can see why a card landed where it did rather than only seeing the final number. CheckCOA pulls the Report Card details into your result. The Heat Map itself is rendered on MBA's own verification page, so open the provider page from your result when you want to see it.
The graded card's details and the MBA grade. CheckCOA surfaces these fields in your result when available.
MBA's breakdown of the key condition issues behind the grade. View it on MBA's own verification page.
MBA's count of how many of a card it has graded. Not part of the CheckCOA result.
This is the part that confuses people. MBA Crossover Grading applies to cards already graded by another company, so a crossover item can carry both an MBA designation and the original PSA, SGC or BVG certificate number. MBA's own verification tool accepts either the MBA cert number or the third-party grader's cert number on crossover items. On CheckCOA, use the MBA serial number on this page. If all you have is the original grader's number, run it on that grader's page instead, because that is the database it belongs to.
Enter it here. This page checks MBA's records for the Report Card details.
Use the PSA graded cards lookup. A PSA cert number resolves in PSA's database, not MBA's.
Check them separately. Two records for one card is normal on a crossover slab, and the details should agree.
MBA Grading is a real, established grading company, and its founder's background is verifiable: Mike Baker was PSA's first employee and its Director of Grading for more than a decade. What collectors debate is not whether the company is genuine but how the market prices it. Opinions in the hobby vary on whether an MBA slab or crossover designation carries the same resale premium as PSA, BGS or SGC, and that is a market question rather than an authenticity one. Either way, a verified serial number tells you the record exists and matches the card, which is what a lookup is for.
PSA is a primary grading and encapsulation company with the largest population and the deepest resale market. MBA grades raw cards too, but a large part of what it does is review and crossover work on cards that are already slabbed by someone else, with the Heat Map explaining the condition issues behind a grade. They are not interchangeable: a PSA cert number resolves in PSA's database and an MBA serial number resolves in MBA's, even when both describe the same physical card.
Counterfeit slabs, reused certificate numbers and swapped labels appear on marketplace listings, and a crossover card carrying two numbers gives a bad actor one more thing to blur. CheckCOA screens every MBA lookup against a growing database of known fake, stolen, reused and compromised certificate numbers to help reduce that risk.
A clean result is not a guarantee of authenticity. New fakes appear every day, so always compare the label, the card, the holder and the seller history before buying.
Use this MBA cert lookup for MBA graded cards and MBA crossover slabs, especially when checking a marketplace listing or a high-value card before purchase.
Enter the MBA Grading serial number from the slab label to pull the Report Card details, and screen it with free Fraud Alert protection.
Use these practical checks to choose the right lookup, read the result and decide when the item needs closer review.
Yes. Verifying an MBA serial number on CheckCOA is free and needs no account. Enter or scan the number to check the MBA record when available and screen it against Fraud Alerts for known fake, stolen, reused or compromised numbers.
The MBA Heat Map is MBA's transparency feature. Instead of showing only a final grade, it highlights the key condition issue or issues behind that grade, so you can see what held the card back. CheckCOA surfaces the MBA Report Card details in your result, while the Heat Map itself is rendered on MBA's own verification page, so open the provider page from your result to view it.
It is the record MBA publishes against a verified serial number: the identifying details of the graded card together with the MBA grade. CheckCOA pulls those details into your result when they are available from the provider source.
MBA's own verification tool accepts either the MBA cert number or the third-party grader's cert number on MBA Crossover Grading items. On CheckCOA, enter the MBA serial number on this page. If you only have the original grader's number, run it on that grader's page instead, because that number lives in that grader's database.

PSA is a primary grading and encapsulation company with the largest population and resale market. MBA grades raw cards as well, but much of its work is review and crossover grading on cards already slabbed elsewhere, with the Heat Map explaining the condition issues behind a grade. The two numbering systems are separate, so a PSA cert resolves in PSA's database and an MBA serial in MBA's, even for the same card.
On the MBA slab label. MBA serial numbers are numeric and typically 9 to 11 digits. Enter the digits exactly as shown on the label.
Usually a typo in the serial, a number from a different grader, or a record that is not available from the provider source. A no-result does not automatically mean the slab is fake, but compare the label, the card and the holder carefully before buying.
Yes. CheckCOA supports camera scan, image OCR and manual entry. Review the detected number before verifying, because OCR can misread a glare-affected or angled label.
No. CheckCOA is an independent verification tool. It helps you check provider records when available, organizes your checks in one place, and adds Fraud Alert checks against known fake, stolen, reused or compromised numbers.
Yes. Every MBA 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.
