If you ever scroll through social media or visit auction sites, you have undoubtedly seen them: Pokémon cards in a sturdy, transparent plastic sleeve with a red and white label on top. These are "slabs", and in most cases, they have been graded by the PSA (Professional Sports Authenticator) .
For both the novice hobbyist and the seasoned investor, PSA grading has become the gold standard. But what exactly does it entail, why are Japanese Pokémon cards in a PSA holder often worth so much more, and is it worth sending in your own collection? In this article, we dive deep into the world of card valuation.
What exactly is PSA grading?
PSA grading is an independent process in which an expert assesses the physical condition of a card. PSA, based in the United States, is the world's largest and most trusted authority in this field. When you send a card to them, it undergoes a rigorous inspection process.
The map is checked at four crucial points:
-
Centering: Is the artwork exactly in the middle of the card, or is the border thicker on one side than on the other?
-
Corners: Are the corners perfectly sharp and round, or are there white spots (whitening)?
-
Edges: Are the edges cleanly cut, or do you see minor damage or "silvering"?
-
Surface: Are there scratches on the holo pattern, fingerprints, or dents in the cardboard?
After the inspection, the card is given a score from 1 to 10 and sealed in an ultrasonically welded holder (the slab). This protects the card against UV light, moisture, and physical damage.
Why collectors choose graded Japanese Pokémon cards
It is no secret that the demand for Japanese sets has skyrocketed in recent years. Anyone looking to collect Pokémon cards at the highest level almost always ends up with Japanese releases. There are specific reasons why PSA grading and Japanese cards are a perfect match:
The hunt for the PSA 10 "Gem Mint"
Japanese cards are known for their superior print quality. Factory tolerances in Japan are stricter than those for English cards. This means that a card from a Japanese Pokémon booster box has a statistically higher chance of achieving a PSA 10 (Gem Mint) score. For collectors, a "10" is the ultimate goal; it is proof that the card is in near-perfect condition.
Authenticity and certainty
Unfortunately, counterfeits sometimes appear on the market. A PSA label contains numerous authenticity features, such as a unique serial number and a QR code that links directly to the PSA database. When you buy a graded card from a reliable shop like CardDash, you know with 100% certainty that you have an authentic product in your hands.
The investment perspective: Value and liquidity
Many people want to invest in Pokémon cards as an alternative asset. Grading plays a decisive role here.
The jump in value: Raw vs. Graded
A "raw" (ungraded) card may look beautiful, but there is always room for discussion regarding its condition. As soon as a card receives the PSA 10 label, that uncertainty disappears. It is not uncommon for a PSA 10 card to be worth three to ten times more than an ungraded example. Even a PSA 9 (Mint) often retains a stable premium compared to individual cards.
Market liquidity
Graded cards are much easier to sell. Because the condition is objectively determined, buyers worldwide dare to pay higher amounts without first physically holding the card. This makes PSA slabs the most "liquid" form of Pokémon investment.
Expert tip: When investing, pay particular attention to popular Japanese sets such as VSTAR Universe or Pokémon 151. The Special Art Rares (SARs) from these sets are highly sought after by collectors worldwide in PSA 10.
Trends: What to look out for in 2026?
The collectibles market continues to evolve. In 2026, we see that collectors are becoming increasingly critical. A few key trends:
-
Pop Reports: Collectors are increasingly looking at the "Population Report". This indicates how many units of a specific card have already received a PSA 10. The lower this number, the more exclusive (and often more expensive) the card.
-
Vintage vs. Modern: While vintage cards (such as the Base Set) remain stable classics, there is tremendous growth in "Modern Waifu" cards and Full Art Trainers from the Scarlet & Violet era.
-
Sequential Sets: It is becoming more popular to collect sets of cards with consecutive serial numbers at PSA. This adds an extra layer of uniqueness to a collection.
Are degrees always worth it? The risks
Although the benefits are significant, it is important to remain realistic. Grading costs money (service fees) and time (shipping and processing times).
-
Low grades: A card that comes back as a PSA 6 or 7 is often worth less than the cost of the grading itself. Therefore, always inspect your cards with a loupe and bright light before sending them in.
-
Upcharges: If you submit a card to a cheap "tier" and it turns out to be worth thousands of euros after grading, PSA may charge an additional amount (upcharge).
-
Shipping: Sending to the US involves risks and costs regarding insurance and customs.
Frequently Asked Questions (FAQ)
1. What is the difference between PSA 9 and PSA 10? A PSA 10 is "Gem Mint", which means the card is virtually perfect. A PSA 9 is "Mint" and may have one minuscule flaw, such as a very small white dot on the corner or centering that is not quite perfect (e.g. 60/40).
2. How long does the process take at PSA? This depends on the chosen service level. "Bulk" shipments can take several months, while "Express" services are back within a few weeks.
3. Can I also have an unopened Pokémon booster box graded? PSA primarily grades individual cards and booster packs. For grading complete booster boxes, other specialized companies are often consulted, although the market for graded packs (especially vintage) is also very large.
Conclusion
PSA grading is much more than just a number on a label; it is a way to immortalize the history and quality of a card. Whether you want to collect Pokémon cards for your own enjoyment or invest in Pokémon cards for the long term, PSA offers the necessary security and appreciation.
For those who prefer not to run the risk of sending cards themselves, buying pre-graded slabs is an excellent option. This way, you know exactly what you are getting and can immediately enjoy the beauty of a perfect Japanese card.
