PSA (Professional Sports Authenticator) is one of the most popular services for grading trading cards, from Pokémon and Magic: The Gathering cards to baseball cards. Once the cards are graded, they come in branded plastic slabs that indicate the card’s authenticity and quality, which helps raise the card’s value—and makes them a common target for scammers. Luckily, there are key signs you can check to tell if a PSA slab is real. We’ll tell you how to spot fake PSA slabs and give you tips on how to avoid fakes while shopping.

How can you tell if a PSA slab is fake?

Trading card collector Chris Frey says a hologram won’t appear when you shine a black light on the label of fakes. Fake PSA slabs often look cloudy or frosted, while real slabs are clear. The plastic might also feel flexible and lightweight on fakes, while real slabs are durable and substantial.

What to Look For to Spot Fake PSA Slabs

1
UV logos Starting around 2012, PSA added UV marks to the front and back labels on the slab. Simply use a black light to see if the marks are present. On the front of the label, “PSA” is repeatedly printed in a line across the top: the “PSA” in the center is large, and the “PSA” logos on either side alternate between upside down and right side up.^{[1]

Research source} On the back of the label, there are six UV “PSA” logos around the large, silver “PSA” logo on the left-hand side: three UV “PSA” logos are above it, and three are below it.^{[2]

- Signs the slab is fake: One or both of the UV marks are missing from the front and back labels. Or, the marks might be slightly off. For instance, the “PSA” logos might not alternate on the front, or there may be fewer than six logos on the back. If you shine a black light on the label, the hologram won’t show up, according to Frey.^{[3]

Illumination effect logos PSA slabs have two silver “PSA” logos with a branded “illumination effect” on the front and back labels, which gives them a two-toned look.^{[4]

Research source} When you move the slab in the light, the silver logos shift from light to dark (like an “on/off” light switch).^{[5]
X
Research source} The front logo is in the bottom center of the label and connects to the red border, while the back logo is in the top center of the label.
- Both silver logos also have tiny “PSA” logos written across the surface. These can be difficult to see without a magnifying glass or jeweler’s loupe.
- Signs the slab is fake: The silver “PSA” logos do not have the illumination effect. Instead, they may simply look like shiny, holographic logos. They might also be missing the tiny “PSA” logos inside.

PSA logo texture PSA slabs are printed with a raised “PSA” logo on the bottom right corner of the plastic on both the front and back. When you run your finger over the “PSA” logo, you’ll feel it.^{[6]
X
Research source}
- Signs the slab is fake: The raised “PSA” logos are missing from the front and/or back. Or, they might be placed in the wrong spot (e.g., bottom left corner or top right corner).

Label ink PSA also prints a “fugitive ink” graphic on the white parts of the front and back label. The bluish ink is very subtle and forms the “PSA” logo, which is easier to see on the front label. This ink is supposed to help prevent label washing.^{[7]

5
Certification number Every PSA-graded trading card gets assigned a certification number, which is printed on the bottom right corner of the front label. To help ensure the slab is real, make sure the certification number matches the card in the slab. To do this, go to PSA’s Cert Verification page and type in the certification number.
- Warning: This method isn’t 100% accurate. Unfortunately, some scammers print real certification numbers on fake slabs, so when you type in the certification number, the real card pops up.^{[9]

  Research source}
- Signs the slab is fake: The certification number doesn’t exist on PSA’s website, or the certification number pulls up a different card.
6
Barcode or QR code PSA slabs also have a barcode and QR code on the label that you can scan to verify the card’s certification number. Simply download the PSA app, go to “Scan a Card,” and either scan the front label or the QR code on the back label to pull up the card’s certification details.^{[10]

- Warning: This method isn’t 100% accurate, as some scammers print real barcodes and QR codes on fake slabs. When you scan either code, the real card pops up.
- Signs the slab is fake: The certification number doesn’t exist on PSA’s website, or the barcode or QR code pulls up a different card.
7
Plastic clarity PSA slabs are made with clear, smooth plastic that’s free from any frosting, cloudiness, or scratches. The slabs are also designed to be tamper-evident. If someone breaks open the sonic weld holding the slab together, the plastic will frost or grow cloudy along the edges, and there may be visible cracks.^{[11]

Research source}
- Signs the slab is fake: The plastic looks cloudy or frosted, and is covered in visible cracks or fractures. This can also be a sign that a real PSA slab was tampered with, and that the card inside may be fake.
8
Plastic quality PSA is known for their durable and hard plastic slabs. They have a substantial feel with a noticeable weight to them. However, PSA designs the plastic to change if the slab is tampered with. If the slab is opened, the plastic feels flexible rather than hard.^{[12]
X
Research source}
- Signs the slab is fake: The plastic feels low quality: it might feel lightweight and easy to damage. If the plastic feels flexible, this can also be a sign that a real PSA slab was tampered with, and that the card inside may be fake.
9
Card insert edges The edges of the slab where the card is held in place are sharp, rectangular edges rather than rounded ones. Even if the card itself has rounded edges, like a Pokémon card, the plastic edges of the slab are sharp.^{[13]
X
Research source}
- Signs the slab is fake: The card insert edges are rounded rather than perfectly straight.
10
Font PSA uses a signature font on the slab labels. The font is black, sans-serif (for instance, the “G” has no tail), and sharp (for instance, the corners of a “2” are sharp, not rounded). Additionally, all of the letters are capital letters and in a consistent size.
- Signs the slab is fake: The font looks off compared to real slabs. It may use serifs, be a different color from black, or contain lower-case letters. Additionally, the font might be too large or too small.
11
Print quality The labels on PSA slabs are always perfectly printed. The logos, font, bar codes and QR codes, and the label itself are clear, sharp, and easy to read. There are no smudges or blurry text and logos.
- Signs the slab is fake: The print quality appears poor. The logos, font, and codes may look blurry or hard to read.

1
Compare pictures and videos of the slab to real slabs. If you’re looking for PSA-graded cards online, always thoroughly look over the pictures to ensure the slab is real. Check all of the signs mentioned above, like the UV logos, illumination logos, raised logo, and label graphic. Ask the seller to provide videos of the slab to help verify these hallmarks.^{[14]

- If possible, shop for PSA-graded cards in person. Authenticating slabs in person is typically easier to see the tells that a slab is real or fake. Plus, holding and feeling the slab can help tell you if it’s real or not.
- If the seller doesn’t provide good-quality photos or videos, ask them to send you better examples. If they refuse to, that’s a red flag that they’re selling a fake slab.

Check the card itself to ensure it’s real. Of course, it’s important to make sure that the card in the slab is real, as some scammers may open real slabs and replace the card with a fake one. In general, check the logos, font, print quality, and other identifying features on the card to ensure it’s real. Compare the photo of the card to a real image of the card—there are many databases online that show official card images (like for Pokémon, Magic: The Gathering, and Yu-Gi-Oh!).

Make sure the price seems right. Be wary of low prices, especially if the card you’re looking at is highly sought after. If the price of the slab seems too good to be true, this can be a red flag that either the slab itself or the card is fake.
- Always look up the card you want to buy online to get a sense of how much people are charging for it.
- For instance, if you’re trying to value a Pokémon card, look it up on a card-selling site (like TCGPlayer) or eBay to see how much it typically sells for.
4
Buy from trustworthy sellers. Always vet the seller you want to buy from to ensure they’re reputable and reliable. Read through their reviews online to ensure there are no red flags, like people receiving fake cards or not receiving refunds or returns. It’s best to shop from sellers who have been around for a while and who’ve made many sales.
- If you have any questions for the seller, message them. If they’re happy to answer your questions or relieve your concerns, that’s a green flag.
- On the other hand, if they ignore your messages or seem unwilling to help you, that’s a red flag, so shop somewhere else.
- Always make your purchase with a credit card, if possible. Credit cards have better protection than debit cards or cash. If it turns out the slab and/or card is fake, you can file a dispute with your credit card company to get your money back.^{[15]

- PSA notes that if a seller has an authentic PSA slab on their hands, they should have no problem sending the item to PSA to check it over. However, if the seller is hesitant or unwilling to do this, that’s a red flag that they might be selling a fake item.
- Remember, you’re buying something with your hard-earned money! Most sellers should have no issue with you wanting to confirm that what you’re getting is authentic.
