How to Verify a PCGS or NGC Graded Coin

November 13, 2026

Quick answer: Every PCGS and NGC holder carries a unique certification number. Enter it at pcgs.com/cert or ngccoin.com/certlookup, then check that the coin, grade and label in front of you match the record and any photos. A match is a strong sign the holder is genuine, but it does not prove the coin hasn’t been swapped into a fake slab, so look at the holder too.

Where do I find the certification number?

The certification number is printed on the label inside the holder, usually near the barcode. It is unique to that one coin. NGC numbers often include a hyphen, such as 1234567-001. PCGS numbers are a single string of digits.

Write the number down exactly as printed. Don’t trust a number from a listing or a photo caption alone. Read it from the actual label if you can. If you are new to labels, our coin label guide shows where each detail sits.

How do I look up a PCGS coin?

Go to pcgs.com/cert or open the free PCGS Cert Verification app.
Enter the certification number. In the app you can also scan the barcode.
Compare the result with the label: date, mint mark, denomination, grade, designation and any label variety.
If the record includes images, compare them with the coin in the holder.

Newer PCGS holders also contain an NFC chip. Tapping a phone to the holder opens the certification record. Each tap creates a one-time code that PCGS checks against a cloud service, which makes the chip hard to copy. Holders with the chip show an NFC symbol on the holder. PCGS warns against adding a second NFC sticker to these holders, because the two tags interfere.

How do I look up an NGC coin?

Go to ngccoin.com/certlookup or use the NGC mobile app.
Enter the certification number and the grade. The hyphen is optional. In the app you can scan the barcode.
Compare the description and grade with the label.
Compare the obverse and reverse photos. NGC has images for most coins it has graded since October 2008.

Newer NGC holders have a hologram on the back with a QR code and an eight-digit security code that are unique to that coin. Scanning the QR code opens that coin’s record in NGC’s verification tool.

Also watch for alerts. NGC may flag a record with a notice such as “possible counterfeit holder” or “reported stolen.” If you see one, stop and contact NGC.

What should match?

A lookup only helps if you check the details. Go through this list:

The coin: date, mint mark and denomination are the same as the record.
The grade: the number and prefix (MS, PF/PR or SP) match exactly.
Designations: notes like First Releases, Early Releases, Ultra Cameo or Deep Cameo appear on both.
The label: a special label, such as a hand-signed label, matches what the record shows.
The photos: spots, toning, marks and the position of the coin look the same. Toning and tiny marks make each coin’s photos distinctive.

What holder features should I check?

Both services build security features into their holders and labels. Here is what each one describes publicly.

Feature	NGC	PCGS
Online lookup	ngccoin.com/certlookup (number + grade)	pcgs.com/cert (number)
Mobile app	NGC app, barcode scan	PCGS Cert Verification app, barcode scan
Phone tap or scan	QR code on the rear hologram (newer holders)	NFC chip with one-time code (newer holders)
Holder security	Hologram on the back with covert and overt features; ultrasonically welded seal	Covert and overt features; stronger weld designed to show tampering
Label security	UV watermark, holographic foil, microprinting	Gold Shield labels carry a hologram; some show micro-text and color-shifting features
Coin images	Most coins graded since October 2008	TrueView photos when they were included in the grading order

Look at the holder itself. The edges should be sealed all the way around, with no cracks, gaps, glue or pry marks. The label should be crisp and sit straight. Hold it next to a holder you know is genuine if you can.

Are counterfeit slabs a real problem?

Yes. They are not common, but they exist. Counterfeiters have made fake holders that copy the look of real ones and reuse the certification number of a genuine coin. That is why NGC has an alert for a counterfeit holder carrying the same number as a real coin.

This is the trap: a fake slab can pass a number lookup, because the number is real. The photos are what catch it. If the coin in the holder doesn’t match the grader’s images, walk away. NGC also states that its guarantee does not cover coins in counterfeit or tampered holders.

What does verification prove, and what doesn’t it?

A successful lookup tells you that the grading service issued that number for a coin with that description and grade. With matching photos, it is strong evidence that you are looking at the coin they graded.

It does not prove that:

the holder in your hand is genuine, if no photos exist to compare;
the holder has never been opened and resealed;
the coin hasn’t been damaged since grading, for example by a cracked holder;
the coin is worth a certain amount. Grade and value are different questions.

When in doubt, contact the grading service directly. NGC says there is never a charge to contact it.

Frequently asked questions

Is a cert number lookup enough to trust a coin?

Not by itself. A lookup confirms the number exists. Comparing the grader’s photos, the label and the holder is what confirms the coin is the one that was graded.

What if the lookup shows a different coin or grade?

Treat it as a red flag. It may be a typo on your end, a label error or a fake holder. Recheck the number, then contact the grading service before you buy or sell.

Can I verify an NGC coin without knowing the grade?

NGC’s lookup asks for both the certification number and the grade, which are both printed on the label.

Can I verify a coin before I buy it online?

Yes. Ask for the certification number and clear photos of both sides of the holder, then look the number up and compare. When the coin arrives, check it again with the holder in your hand.
