The Complete Guide to Buying Graded Video Games in 2024
The market for graded video games has exploded over the past five years. Whether you're a collector looking to protect a childhood favorite or an investor eyeing blue-chip assets, understanding how grading works—and where the pitfalls lie—can save thousands of dollars. This guide breaks down exactly what the numbers on those sealed cases mean, which companies actually matter in 2024, and how to spot a deal worth taking versus a trap worth avoiding. No fluff. Just what you need to make smart buys.
What Do Video Game Grades Actually Mean?
A graded video game is a sealed or complete-in-box (CIB) game that's been authenticated, inspected, and assigned a numerical condition score by a professional third party. That number—usually between 1.0 and 10.0—reflects the physical state of the box, cartridge or disc, and any included materials like manuals or posters.
Here's the thing: not all 9.8s are created equal. WATA Games (now part of Certified Collectibles Group) uses a 10-point scale with .5 increments. CGC Video Games employs a similar system but adds plus grades (9.8+, for instance) for games that exceed their numerical tier without quite hitting the next whole number. VGA (Video Game Authority) pioneered the space but now uses a 100-point scale alongside the traditional 10-point system.
The grade breaks down into three core components:
- Seal rating — How intact is the factory shrink wrap or seal? Any tears, holes, or wear?
- Box condition — Corners, edges, surface wear, and structural integrity.
- Internal contents — Manuals, inserts, cartridges, discs—are they present and pristine?
Worth noting: a "sealed" designation means the game has never been opened. A "CIB" (complete in box) game has been opened but contains all original materials. The price gap between a sealed 9.4 Super Mario Bros. and a CIB 9.4 can be tens of thousands of dollars. The catch? Not every old game in plastic wrap is factory sealed—re-seals happen, and they're the fastest way to lose money in this hobby.
Which Video Game Grading Company Should You Trust?
In 2024, two companies dominate the graded video game market: WATA Games and CGC Video Games. Both operate under the Certified Collectibles Group umbrella and both use standardized grading scales backed by professional grading teams. VGA (Video Game Authority) remains in operation but handles significantly lower volume and primarily serves European collectors.
| Company | Scale | Turnaround Time | Best For |
|---|---|---|---|
| WATA Games | 1.0–10.0 (0.5 increments) | 60–90 days | Sealed vintage (1985–2000), high-value investments |
| CGC Video Games | 1.0–10.0 (+ grades available) | 45–75 days | Modern games (PS4/Xbox One era and newer), CIB submissions |
| VGA | 1–100 and 1.0–10.0 | 30–60 days | European collectors, PAL region games |
That said, raw (ungraded) games still trade heavily on eBay and through private collector networks. The grading premium—what you pay extra for that plastic case and number—ranges from 30% to 300% depending on the title's rarity. A common PlayStation 2 game graded 9.8 might fetch $150 raw but only $180 graded. Not worth the grading fee. A sealed The Legend of Zelda: Ocarina of Time graded 9.4? That jumps from roughly $2,000 raw to $8,000+ in a WATA case.
Authentication matters more than the grade itself. Counterfeit games plague the market—reproduction cartridges passed as originals, re-sealed boxes, "married" components (mixing a genuine box with a fake insert). Professional graders catch most fakes. Most—not all. Buy the seller before you buy the game. A 9.6 from a reputable dealer carries more comfort than a 9.6 from a zero-feedback eBay account.
Is Buying Graded Video Games Worth the Investment?
Graded games have outperformed traditional collectibles like comic books and sports cards since 2019. Heritage Auctions reported over $30 million in video game sales in 2023 alone, with graded sealed titles driving the majority of high-value transactions. A sealed Super Mario Bros. (NES) sold for $2 million in 2021. A Legend of Zelda prototype fetched $55,000.
But here's the thing: past performance doesn't guarantee future returns. The graded game market cooled significantly in 2022–2023 after overheating during pandemic lockdowns. Prices for common sealed Nintendo 64 titles dropped 40–60% from their peaks. The winners? Rare variants, first-print titles, and historically significant games. The losers? Mass-produced sports titles and common releases everyone assumed would "go up."
The investment case rests on three factors:
- Scarcity — Limited production runs, regional exclusives, and promotional copies genuinely don't exist in large quantities.
- Cultural significance — Games that defined generations—Super Mario 64, Final Fantasy VII, Halo: Combat Evolved—maintain demand across collector generations.
- Condition rarity — Factory-sealed games from the 1980s and 1990s survived in small numbers. A 9.8 grade implies near-perfection after 30+ years. That's genuinely hard to find.
The catch? Liquidity. Selling a graded game takes weeks or months. Auction houses like Heritage charge 10–15% seller's fees. eBay takes 13.25% plus payment processing. Private sales require trust—or middlemen who take their cut. You're not day-trading here. You're parking capital in plastic cases and waiting.
Where to Actually Buy Graded Games
Most collectors start on eBay—and most collectors overpay. eBay's "Buy It Now" prices typically sit 15–30% above market value because sellers anticipate offers. The real deals happen through:
- Heritage Auctions — Monthly video game sessions, authenticated listings, but buyer's premiums run 20–25%.
- Facebook collector groups — "Sealed Video Game Collectors" and similar communities with vetted members and middleman services.
- Collector conventions — TooManyGames, Portland Retro Gaming Expo, and Midwest Gaming Classic allow in-person inspection before purchase.
- Private networks — Established dealers like Sealed Games (yours truly) who source directly from estate sales and original owners.
Always verify the certification number. WATA and CGC both maintain online databases—enter the certification number from the case label and confirm the game details match. If the database shows a different game, or no result, walk away. No exceptions.
Red Flags and Common Scams
The graded game market attracts money. Money attracts bad actors. Watch for these warning signs:
Re-holder scams. A cracked or opened case means the grade is meaningless. The plastic should be crystal-clear, sealed along the edges, with no gaps or tamper marks.
VGA "90+" confusion. Some sellers list VGA 90+ (their top tier) as equivalent to WATA 9.8 or CGC 9.8. It's not. VGA's 90+ roughly equals WATA 9.4–9.6. Know the conversion before comparing prices.
Modern reprints sold as vintage. Nintendo re-released classic NES and SNES titles through the "Classic Series" in the late 1990s. These aren't original prints. The grading case will specify "Classic Series" if submitted honestly—but raw sellers often omit this detail.
Grade inflation. Early WATA submissions (2017–2019) sometimes graded tougher than current standards. A 9.4 from 2018 might present better than a 9.6 from 2024. Pop reports—public databases showing how many copies exist at each grade—help identify true scarcity.
The Maintenance Reality
Graded games don't require much care, but they do require some. UV light degrades box art and manuals over decades—store cases away from direct sunlight. Temperature fluctuations cause plastic expansion and contraction, potentially stressing seals. A climate-controlled room (65–75°F, 40–50% humidity) preserves both the game and the case integrity.
Don't stack graded cases. The weight distribution can stress lower boxes. Don't clean cases with ammonia-based products (like Windex)—they cloud acrylic over time. Distilled water and a microfiber cloth handle dust just fine.
"The best graded game purchase is one you'd be happy owning at zero appreciation. If the nostalgia or display value justifies the price, any upside is a bonus."
Insurance matters for collections exceeding $10,000. Standard homeowner's policies rarely cover collectibles at full value. Collectibles Insurance Services and Hagerty offer specialized policies with agreed-value coverage and lower deductibles. Document every purchase with photos, receipts, and certification numbers.
Start small. A $200 graded Game Boy game teaches you inspection skills, market dynamics, and seller vetting without risking retirement funds. The collectors who thrive in this space aren't the ones who bought a $50,000 Stadium Events on day one. They're the ones who spent years learning what separates a 9.2 from a 9.6, who can spot a re-seal from across a convention hall, who know that patience beats FOMO every single time.
