Is Professional Game Grading Worth It? WATA and VGA Explained

Professional game grading is a genuine tool for a specific type of collector and a waste of money for most others. That is not a cynical take — it is what the math produces when you apply submission fees and turnaround timelines to the realistic auction outcomes for a given title. The market for graded games peaked sharply in 2020 and 2021, pulled in a wave of speculation, and has since corrected to something closer to its historical baseline. Understanding what a grade actually measures — and what it does not — is the prerequisite for any honest decision about whether to submit. If you are still pricing grading decisions against 2021 Heritage auction records, you are working from the wrong data. Before going further, the underlying question of what your collection is worth ungraded is worth resolving first — see how much your retro game collection is worth for that foundation.

What Do WATA and VGA Actually Grade?

Both WATA Games and Video Game Authority (VGA) grade the exterior condition of a game’s packaging — the box, the shrink seal (if the game is sealed), and the cartridge or disc case on visible surfaces. Neither service opens the packaging. Neither verifies the PCB inside the cartridge, authenticates the internal hardware, or assesses playability. You are paying for an assessment of what can be seen without destructive inspection.

WATA grades on a 100-point scale, though the practical range in active trading sits between roughly 40 and 100. The numeric grade is paired with a letter suffix for seal quality: A+ (seal fully intact with no visible defects), A, B, and C in descending condition. A game graded 85 A+ and a game graded 85 B represent meaningfully different market positions — the seal grade carries real weight with serious buyers.

VGA uses a similar numeric structure. The scale is comparable, though the grading criteria and the specific way condition factors are weighted differ between the two services. Neither service has published a fully transparent rubric, which means graders exercise judgment, and results on borderline specimens can surprise submitters in either direction.

The professional grading market is, in practical terms, a sealed-game market. Loose cartridges can be submitted, but the collector community has not organized around graded loose copies the way it has around graded sealed examples. A graded loose cartridge rarely commands a meaningful premium over a well-documented raw copy. The economic case for grading is built almost entirely on sealed games with meaningful scarcity and genuine collector demand.

Once a game is graded, it is sealed inside tamper-evident acrylic — a process known in the collector community as “slabbing.” The slab cannot be removed without permanently destroying the grade. If you have any interest in playing the game, do not grade it.

WATA vs. VGA: What Is the Difference?

WATA Games was founded in 2018 and moved quickly to establish a partnership with Heritage Auctions, the dominant platform for high-value retro game sales. The consequence of that relationship is that WATA grades have become the standard denomination at Heritage and on most major collector platforms. When you see record auction prices cited in coverage of the graded game market, nearly all of them involve WATA-graded material. WATA offers multiple fee tiers with faster turnaround available at premium cost — standard tier runs 6 to 12 weeks; expedited tiers compress that to 2 to 4 weeks at significantly higher per-item cost.

VGA has a longer history, having operated since approximately 2000 — well before the current graded game market developed into its present form. VGA established the concept of professional game grading for this hobby, and a segment of the collector community specifically collects VGA-graded material as its own category. VGA grades remain accepted and trade actively. However, VGA has lost substantial auction market share to WATA in the years since WATA’s Heritage partnership took hold, and the liquidity difference is real in the current market.

The practical difference for a seller evaluating which service to use: WATA grades are more liquid in today’s auction environment. A WATA 85 A on a desirable title has a well-established market with multiple active buyers. An equivalent VGA grade on the same title may perform comparably with the right buyer but will have a narrower active market at any given moment. For collectors who have been building a VGA-graded set, there is no reason to crack slabs and resubmit — the collector-set value is real. For someone grading a game for the first time with the goal of maximizing auction returns, WATA is the more straightforward choice in the current environment.

When Does Professional Grading Make Financial Sense?

The math is not complicated, but it requires honest inputs.

Standard WATA submission fees run $50 to $100 or more per item depending on tier selection, and that fee covers only the grading service — shipping costs and insurance in both directions are separate. At the standard tier, plan for a 6 to 12 week turnaround from submission to return. That is capital tied up for three months minimum, plus the submission cost.

A useful working rule: a sealed game needs a realistic ungraded value of at least $200 to clear the minimum threshold where grading math can work. At that level, a strong grade — 85 or above with a solid seal grade — can generate demonstrable lift at auction. A sealed game in that position that grades at 85 A+ might achieve $400 to $600 at a competitive Heritage session where it would have sold raw for $250 to $300. The premium justifies the fee and the wait.

Below that threshold, the numbers collapse. A sealed game with an ungraded value of $80 does not generate enough auction premium at any realistic grade to clear a $75 submission cost. At $150 ungraded value, the margin is thin enough that a grade below 85, or a weaker seal grade, erases it entirely.

Grades below 80 deserve specific attention: they frequently work against the seller rather than for them. A grade in the 60 to 75 range does not signal “this is a collectible item with documented condition” — it signals “this is a damaged item with documented problems.” A well-photographed raw copy in similar physical condition often sells for more than a formally graded copy in the same range, because raw buyers can evaluate the photos and make their own judgment, while the grade forecloses that interpretation. The slab makes the condition verdict permanent and visible to every buyer who looks.

The carry cost matters as well. Slabbed games are illiquid assets. You cannot decide in month four that you want to play the game — cracking the slab destroys the grade permanently, and the game returns to the raw market at whatever its ungraded condition would command. Grade only games you are certain you will not want to play.

The 2021 Bubble and What the Market Looks Like Now

The 2020-2021 period produced a wave of auction records for graded games that drew widespread media attention. Super Mario Bros., The Legend of Zelda, and Super Mario 64 each achieved prices in the hundreds of thousands of dollars at Heritage. These results were genuine in the sense that the transactions occurred, but they reflected a convergence of conditions — pandemic-era liquidity, speculative momentum, and aggressive bidding — that were not indicators of stable long-term value.

The correction that followed was significant. Auction averages for graded material in many categories are down 30 to 60 percent from 2021 peaks. The speculative cohort — buyers and sellers who entered the market in 2020 and 2021 primarily because prices were rising — has largely exited. What remains is the underlying collector market for high-grade sealed examples of genuinely scarce titles, which is a real and functioning market but a much smaller and less volatile one than 2021 suggested.

The practical implication: if you set aside a sealed game in 2021 with the intention of grading it because you saw what similar titles were achieving at Heritage, the current auction environment is different. The titles that have held value best are those with genuine scarcity — low print runs, regional variants, titles with documented collector demand that predates the bubble. Common titles that reached bubble-era prices on the strength of media momentum, rather than fundamental scarcity, have corrected harder. NOSTOS handles graded material, but we do not encourage grading as an investment strategy for common titles in the current market.

The Sealed vs. CIB Valuation Layer

One additional variable worth addressing before deciding whether to grade: understanding where a specific title sits in the loose versus CIB versus sealed valuation hierarchy changes the grading calculus. For some titles, the gap between a sealed example and a complete-in-box (CIB) copy is modest — the sealed premium does not justify grading costs. For other titles, the sealed premium is substantial and the grade amplifies it further. The detailed framework for how that hierarchy works is in the loose vs. CIB market intelligence guide.

From the Bench

What we see in the Atlanta market is a consistent pattern: collectors who set games aside during 2021 and are now considering submission are frequently surprised when they run current auction comps. The games are often real candidates — sealed, good condition, legitimate titles — but the price expectations are built from a market that no longer exists at those levels. Before deciding to grade, three questions are worth answering honestly: What is the realistic sealed grade this game will receive, and what is the auction history for that specific grade on this specific title in the past 12 months? Is this title scarce enough that strong-grade copies trade above $300 in the current market? And can you wait 6 to 12 weeks for the result without needing the capital? If the answer to any of those three is uncertain, the economics of grading are not in your favor.

The Bottom Line

Professional grading is a precision tool for a narrow set of sealed, high-value, genuinely scarce titles where a strong grade demonstrably moves the auction price above the submission cost and wait time. For everything outside that set — loose cartridges, CIB games, sealed games with modest ungraded values, common titles regardless of condition — a well-documented raw copy with honest condition photography will sell at the same or higher effective price without the fee, the 12-week wait, or the permanent encapsulation.

If you are trying to assess whether a specific game in your collection belongs in the narrow set where grading makes sense, the best starting point is an honest condition evaluation before you commit to submission. We do that assessment at the counter. Schedule an appraisal at NOSTOS in Duluth before you ship anything to a grading service — knowing the realistic grade range and current auction comps for your specific title costs nothing and can save a significant submission fee.
