The Walrein ex from Power Keepers (card 99/108) trades at dramatically different prices depending on condition grade. A PSA 10 graded copy commands around $1,521, while a PSA 9 drops to approximately $203, representing a sevenfold gap for just one point of grading difference. This card is a Water-type Rare Holo EX with 150 HP, illustrated by Ryo Ueda, and remains one of the more sought-after cards from the Power Keepers era due to its strong artwork and playable nature from the original TCG format.
The price differential reflects how grading agencies assess card condition, not just rarity. A PSA 10 (Gem Mint) exhibits nearly perfect centering, corners, and surface quality, while PSA 9 (Mint) cards show minimal wear but may have slight imperfections. For Walrein ex specifically, this condition sensitivity means buyers need to know exactly what they’re purchasing—a seemingly small cosmetic flaw between grades translates to four-figure differences in market value.

What Determines Market Price for This Specific Card?
Walrein ex’s market value depends on three core factors: grading certification, holo pattern integrity, and print line authenticity. The card originally sold for under $5 at retail, but its competitive playability in mid-2000s tournaments and limited print run pushed demand higher in subsequent years. PSA 9 copies trade at roughly 13% of the PSA 10 price, making this card particularly sensitive to condition assessment accuracy.
The holo pattern on this card is known for showing fingerprints and light scratches more visibly than many contemporaries because of its reflective surface quality. Raw (ungraded) copies in near-mint condition typically sell between $400–$800, depending on the seller’s assessment and buyer confidence in their condition claims. Professional grading removes subjective judgment from the equation, which is why certified copies command premium prices.
How Grading Service Reports Impact Your Card’s Value
Third-party grading from companies like PSA, BGS, or CGC provides authentication and numeric condition scoring that enables price standardization across markets. However, a critical limitation exists: grading standards have shifted over decades. PSA cards graded in 2010 versus 2024 may receive different numerical assessments for identical wear patterns because the company adjusted its standards periodically.
Older Walrein ex cards currently graded PSA 9 might have received a PSA 8 under modern criteria—a warning sign for collectors who overpay for vintage graded cards without researching when they were initially certified. CGC and BGS grading services offer alternatives to PSA, with different reputation scales. Some collectors prefer BGS subgrades (which break down centering, corners, edges, and surface separately), while others view PSA 10s as the market standard for Walrein ex specifically. Regrading costs $15–$30 per card and takes weeks, making it impractical if you suspect your grade is soft or outdated.
Where to Buy and Compare Current Market Listings
TCGPlayer maintains active marketplace listings from multiple sellers, allowing you to compare prices for raw and graded copies side-by-side. As of mid-2026, raw Rare Holo Walrein ex copies there range from $200 for heavily played copies to $700+ for near-mint ungraded examples, with significant seller variance. CardTrader offers a European marketplace presence and sometimes lists international pricing tiers that undercut North American sellers, though shipping costs often eliminate those savings.
eBay’s auction format can yield price discoveries below market average if you’re patient, but watch carefully for seller return policies—counterfeits of high-value Rare Holo cards, while rare, do exist. Dittobase and Sports Card Investor function as price guides rather than retailers, pulling historical sales data to estimate current fair market values. A comparison example: the same PSA 9 Walrein ex might list at $210 on TCGPlayer, $190 on CardTrader (shipped from Germany), and $225 on eBay Buy It Now—differences small enough that shipping costs dominate the decision.
Assessing Raw Copies and Deciding Whether to Grade
Buying an ungraded Walrein ex requires confidence in condition assessment because the upside of submitting a raw card to PSA is offset by turnaround times (currently 15–30 business days for standard service) and the risk of receiving a lower grade than expected. If you suspect a raw copy might grade PSA 9 or higher, the cost to grade ($30 in bulk service) could be justified—but if it grades PSA 8, your $250 purchase becomes a $100–$150 card after paying grading fees, a costly miscalculation. The break-even point for raw Walrein ex occurs around $350–$400.
Below that price, even if it grades PSA 9, you’ve lost money to grading costs. Above $500 ungraded, sellers expect near-PSA 9 condition, so the risk shifts to you. A practical comparison: a $300 raw copy that grades PSA 9 nets you a $200 card after fees; a $600 raw copy that grades PSA 8 becomes a $300 card, eating your profit entirely.
Spotting Counterfeits and Grading Red Flags
Counterfeit Power Keepers cards exist but are uncommon due to the set’s age and relatively low print volume. Tell-tale signs include off-center text on the back, incorrect holo pattern (Power Keepers holos have a distinctive sparkle pattern), and paper thickness that feels thinner or thicker than genuine copies. The Ryo Ueda signature on Walrein ex’s illustration should appear crisp and appropriately sized—blurry or oversized signatures indicate fakes.
Grading can mask damage in ways that raw inspection reveals. A PSA 9 holder might conceal light creasing along the left edge or a small stain on the reverse that wouldn’t justify a lower grade but affects playability and display aesthetics. PSA slabs themselves have evolved in design—older slabs (pre-2018) use different materials than modern ones, and slab inconsistency sometimes signals a reholder’s work rather than original certification. If you’re paying $1,500 for a PSA 10, verify the slab’s hologram is intact and the grade label is perfectly centered inside the case.
Print Line Variations and Special Releases
Power Keepers underwent multiple print runs across regions (Japanese, English unlimited), and later reprints appeared in compilation sets. The 99/108 rare holo exists in standard English and potentially in other language versions, each with separate market tracking.
Japanese versions of comparable Walrein ex cards from the equivalent set (Intense Fight in the Different Dimension) command different price tiers because the Japanese collectors’ market operates on different supply-demand curves than the North American market. Special variations like reverse holos or miscuts from Power Keepers are rarer than the standard 99/108 rare holo, but market demand for variants doesn’t always justify premium pricing. A miscut Walrein ex, despite being technically unique, may sell for less than a flawless PSA 9 because fewer buyers actively seek printing errors compared than seek high-condition holographic copies.
Tracking Price Trends and Timing Your Purchase or Sale
Walrein ex pricing has remained relatively stable for the past 18 months (March 2025–July 2026), with PSA 9 copies fluctuating between $180–$220. Seasonal patterns exist; prices often dip in August (back-to-school season when casual sellers liquidate) and climb in November–December (holiday gift buying).
If you’re selling, timing a graded copy’s listing for late fall can mean $20–$40 more per card compared to summer months, though supply gluts from bulk sellers can invert that pattern. Historical sales records on TCGPlayer and Mavin show that PSA 10 Walrein ex copies have sold as high as $1,800 and as low as $1,200 depending on auction timing and condition of similar competing listings. Your decision to buy at the current $1,521 ask price depends on whether you expect the card to appreciate (unlikely without major tournament nostalgia shifts) or whether you’re collecting for personal enjoyment, where “fair price” matters less than ownership satisfaction.
