PSA 10 vs PSA 9: How to Choose Graded Japanese Pokémon Cards

November 5, 2026

PSA 10 vs PSA 9 guide cover with two graded card cases

A PSA 10 and a PSA 9 of the same Japanese Pokémon card can look almost identical in a photo, yet sell for very different prices. This guide explains what the two grades actually mean, what PSA looks at, and how to decide which one belongs in your collection.

The short version

PSA 10 (Gem Mint) is a virtually perfect card: sharp corners, full gloss, no staining, and front centering of about 60/40 or better.
PSA 9 (Mint) is a superb card with one minor flaw, such as a slight print line or centering of about 65/35.
Buy PSA 10 for the top of the population report and long-term collecting; buy PSA 9 when you want the card in a slab and the best eye appeal for the money.
Always check the certification number on PSA's website. Every card we sell is a Japanese printing graded PSA 10 or PSA 9.

What PSA 10 and PSA 9 mean

PSA (Professional Sports Authenticator) grades cards on a 1 to 10 scale and seals each one in a tamper-evident plastic case, often called a slab, with a label showing the grade and a unique certification number. Only the top two grades appear in our Pokémon Cards collection.

Grade	PSA 10 · Gem Mint	PSA 9 · Mint
Overall	Virtually perfect	Superb, with one minor flaw
Front centering	About 55/45 to 60/40 or better	About 60/40 to 65/35 or better
Back centering	75/25 or better	90/10 or better
Corners	Four sharp corners	Sharp; very minor wear may be allowed
Surface	Full original gloss, no staining	One small flaw allowed, such as a slight print line or very light mark
Typical buyer	Set completers, top-population hunters, long-term holders	Collectors who want a graded copy with excellent eye appeal at a lower price

Centering ratios describe how evenly the border is split. 60/40 means one side's border is 60% of the combined width of the two opposite borders. PSA publishes these standards as guidelines, and the final grade reflects the card as a whole.

The four things graders look at

Centering. How evenly the artwork sits within the borders, front and back. This is the most common reason a near-perfect modern card lands at 9 instead of 10.
Corners. Any whitening, softness or a dinged corner under magnification. Corners are where vintage cards most often lose points.
Edges. Chipping or roughness along the cut, which shows up most on cards with coloured borders.
Surface. Scratches, print lines, dents, fingerprints and the gloss of holo foil. Full-art and textured cards are especially sensitive here.

Collector tipA PSA 9 usually earned its grade because of one thing. Look closely at the photos: if the only issue is slightly uneven centering, the card can look just as good on a shelf as a 10.

Why Japanese cards are worth grading

Japanese Pokémon cards are released first, often with exclusive promos, mirror variants and artwork that never reaches other markets. Many collectors also prize Japanese printings for their print quality and consistent cutting, which is one reason Japanese cards are graded so often.

Things that make Japanese cards different to collect:

Exclusive releases. Prize cards, magazine and event promos, and Japan-only subsets.
Mirror variants. Some special sets include reverse-holo patterns such as Poké Ball and Master Ball mirrors, which are collected as separate cards.
Vintage "old-back" cards. Early Japanese cards use the original Japanese card back. Clean, well-centered examples are scarce, so high grades carry real weight.
Different rarity codes. Japanese cards mark rarity with letters rather than symbols alone, which helps you identify exactly what you are buying (see below).

How to read a PSA label and rarity code

A PSA label for a Japanese card normally shows the year, the game and language, the card name, the card number, any variant name, the grade and the certification number. Our product titles follow the same idea: card name, variant, rarity, card number and grade, for example Volcarona (Master Ball Mirror) R 019/086 PSA 10.

Code	Meaning	What to expect
C / U / R	Common, Uncommon, Rare	Base rarities; mirror variants of these can be very collectible.
RR / RRR	Double Rare, Triple Rare	Pokémon ex and other rule-box cards in the main set.
AR	Art Rare	Full illustration of a Pokémon, often with a story scene. Popular to grade.
SR	Super Rare	Full-art Pokémon and Trainer cards.
SAR	Special Art Rare	The chase illustration cards of modern sets. Centering and surface are critical.
UR	Ultra Rare	Gold-textured cards. Surface scratches show easily, so 10s are harder.
PROMO	Promotional card	From events, magazines, campaigns or products. The number usually ends in a set code such as /SV-P.

Not every era uses every code, and some special sets add their own. The card number (for example 065/150) and the set code printed at the bottom of the card are the most reliable way to match a listing to the exact card.

PSA 10 or PSA 9: which should you buy?

Choose PSA 10 if…: you are completing a graded set, want the best copy you can own, or are collecting with a long-term view. For many modern cards the 10 is the reference copy collectors compare against.
Choose PSA 9 if…: you want the card protected and authenticated, care most about how it looks in a display, or want a sought-after card for noticeably less than a 10.
Check the population…: on PSA's population report. When very few 10s exist (common for vintage cards), a 9 can be among the best copies available. When thousands of 10s exist, the gap between grades often matters less for display.

Collector tipFor vintage Japanese cards, a sharp PSA 9 is often the most realistic top-grade copy. For modern SARs and ARs, centering decides most 9 versus 10 outcomes, so compare the borders in the listing photos.

Checking a slab before and after you buy

Look up the certification number on PSA's official cert verification page. It should show the same card, number and grade as the label.
Inspect the case. The label should sit flat and straight, and the seams should be intact. Light scuffs on the plastic do not affect the grade.
Compare the card to the label. Card name, number and variant on the card itself should match what the label says.
Store it well. Keep slabs upright, out of direct sunlight and away from heat. A slab sleeve or graded-card box prevents case scratches.

Some of our listings use photos supplied with the card, so the certification number in a photo can differ from the slab you receive. If a specific cert number matters to you, email info@sakurastash.com before ordering and we will confirm it.
