🔍 Serial# Lookup

What the MPE serial number is

Every card MPE grades is sealed in a tamper-evident slab with a serial number printed on the label, in the form MPE-12345. That number is the permanent identifier for that exact slab. The grade, the front and back scans taken at grading, the ownership history and every recorded sale are all tied to it, which is what makes a graded card verifiable rather than just a card in a plastic case.

Where to find the serial on a slab

Look at the label along the top of the holder. The serial sits with the grade and the card details — player, year, set and card number. If you are buying online and the seller has not shown the label clearly, ask for a photo of it before you pay: the serial is the only thing that lets you check the slab is real and that the grade on the label is the grade MPE actually issued.

What the lookup shows you

• The player, year, set, subset and card number recorded at grading.
• The grade MPE issued, and the grade name that goes with it.
• The front and back images captured when the card was encapsulated, so you can compare them against the slab in front of you.
• Recent completed eBay sales for the same card, plus quick links out to price guides and comps.

Common questions

The serial returns no results — what does that mean?

Check for typos first, and enter only the digits (you can leave off the "MPE-" prefix). If it still does not resolve, the slab is not in the MPE database. Treat that as a red flag on any purchase and contact MPE before you buy.

Can I look up a card someone else owns?

Yes. The lookup is public and does not require an account. It shows the card and its grade — it does not reveal who holds it unless that collector has opted into the public marketplace.

How do I get my own cards graded and vaulted?

Send them in through MPE grading. Once graded, cards can be stored in the vault under their serial and bought, sold or traded without ever being shipped again.
