CGC Video Game Grading Scale Explained: What Each Grade Means

The CGC video game grading scale runs from 1.0 to 10.0 in 0.5-point increments, with 10.0 representing a perfect, flawless sealed game. CGC (Certified Guaranty Company) adapted this scale from their decades of experience grading comic books and trading cards. Understanding what each grade level means — and how small differences like 9.0 vs 9.4 dramatically affect value — is essential for collectors making submission decisions.

What Is the CGC Grading Scale for Video Games?

The CGC grading scale for video games is a standardized 1.0-10.0 rating system that evaluates the physical condition of sealed video game packaging. CGC assesses seal integrity, case clarity, insert quality, edge condition, and authenticity. Each component contributes to the final numerical grade that appears on the CGC slab label.

CGC 10.0: Gem Mint (Perfect)

A CGC 10.0 Gem Mint grade means the sealed game is virtually flawless under magnification. The seal is pristine with perfect H-seam alignment, tight Y-folds, and zero separation. The case has no scratches, yellowing, or cloudiness. The insert is perfectly centered with flawless print quality. Corners are sharp with no wear. CGC 10.0 grades are extraordinarily rare — less than 1% of submissions achieve this grade.

CGC 9.8: Near Mint/Mint

A CGC 9.8 is near-perfect with only the most minimal imperfections visible under magnification. Perhaps one barely detectable corner issue or the slightest seal softness. These are exceptional specimens that most collectors would call perfect without magnification. CGC 9.8 games command premium prices, often 2-5x more than a 9.4 of the same title.

CGC 9.4-9.6: Near Mint

The 9.4-9.6 range represents Near Mint condition — excellent sealed games with minor imperfections. A 9.6 might have one small area of concern (slight edge softness or minor seal relaxation). A 9.4 allows for two or three minor issues. These are the grades most serious collectors target because they balance strong condition with attainability. The value difference between 9.4 and 9.6 can be 20-50% depending on the title.

CGC 9.0-9.2: Very Fine/Near Mint

Games grading 9.0-9.2 are in very good condition with noticeable but minor wear. You might see light edge wear, slight seal softness, minor case scratching, or small Y-fold relaxation. These games look great on display and still command meaningful premiums over raw copies. A CGC 9.0 is the threshold where grading typically becomes profitable for high-demand titles.

CGC 8.0-8.5: Very Fine

The 8.0-8.5 range shows clear signs of age or handling but the game is still in good overall condition. Expect visible edge wear, seal relaxation, minor cloudiness, or a combination of smaller issues. Grading at this level is only profitable for rare, high-value titles where even an 8.0 in a CGC slab commands a significant premium over raw.

CGC 7.0-7.5: Fine/Very Fine

Games grading 7.0-7.5 have moderate wear that's clearly visible without magnification. Multiple condition issues are present: seal problems, case wear, edge damage, or yellowing. At this grade level, only the rarest titles justify grading costs. Most games at 7.0-7.5 should remain raw unless the title itself is exceptionally valuable.

CGC 6.0 and Below: Fine to Poor

Grades below 6.0 indicate significant condition issues: major seal damage, heavy yellowing, substantial edge wear, or compromised integrity. These grades are reserved for games with obvious defects. Very few games at this grade level benefit from professional grading, as the slab cost ($100-300+) typically exceeds any value increase. The exception is ultra-rare titles where authentication value alone justifies the cost.

How CGC Grades Affect Sealed Game Value

The value curve for CGC-graded games is not linear — it accelerates exponentially above 9.0. A sealed game worth $500 raw might be worth $800 at CGC 8.5, $1,200 at 9.0, $1,800 at 9.4, and $3,000+ at 9.8. This exponential curve is why the difference between a 9.0 and 9.4 matters so much to collectors and investors.

• CGC 9.8+: 3-10x raw value (extremely title-dependent)
• CGC 9.4-9.6: 2-4x raw value for high-demand titles
• CGC 9.0-9.2: 1.5-2.5x raw value for popular titles
• CGC 8.0-8.5: 1.2-1.5x raw value (often marginal after grading costs)
• CGC 7.0-7.5: Rarely worth grading (grading costs may exceed value increase)
• CGC 6.0 and below: Only grade for authentication of rare titles

What Separates a 9.0 from a 9.4?

The difference between a CGC 9.0 and 9.4 often comes down to one or two minor condition factors. A 9.4 might have slightly tighter Y-folds, a marginally cleaner H-seam, or less edge softness. These differences are often invisible without magnification but represent a 20-50% value difference. This is exactly why pre-submission analysis is valuable — predicting which side of the 9.0/9.4 line your game falls on can mean hundreds or thousands of dollars in value.

How to Predict Your Game's CGC Grade

Predicting a CGC grade requires evaluating the same five components graders assess: seal integrity, case clarity, insert quality, edge condition, and authenticity. Experienced dealers develop this skill over years of handling graded games. AI-powered tools like GameMintAI compress that experience into a 30-second photo analysis, predicting grades with 80% accuracy within 0.5 points of actual CGC grades.

Bottom Line

The CGC grading scale is the standard for sealed video game condition assessment. Understanding what each grade means helps you set realistic expectations, calculate ROI before submission, and make informed buying decisions. The key takeaway: grades above 9.0 deliver exponential value increases, making accurate pre-submission grade prediction the most important step in the grading process.
