The two industry standards
WATA Games and VGA (Video Game Authority) are the two third-party services for grading sealed video games. Both encapsulate the cartridge or disc in a hard acrylic case after assigning a numeric grade for box condition and a letter grade for the seal.
How they differ
VGA arrived earlier and used a 0-100 grading scale. WATA launched later, used a more granular A++ to A seal-grade letter system, and benefitted from a high-profile public marketing push during the late-2010s collectible boom. Both services produce widely recognised slabs.
What the seal grade actually means
A WATA seal grade of A++ means the factory shrinkwrap is intact, taut, and shows no compression or wrinkles. A means generally clean. B and below indicate breaks or repairs. The seal grade is independent of the box grade and is often the value driver on high-end pieces.
Choosing a service
For modern sealed grading, both services are widely accepted, but WATA holders trade with a slight market premium on high-grade landmark titles. For older VGA-graded pieces, the slab is well-respected and crossing over rarely produces a meaningful gain. As always, recent realised auction prices for the specific title in the specific holder is the best guide.
Frequently Asked Questions
Is this vintage games guide suitable for beginners?
Yes — this guide is written to be accessible to new collectors while remaining useful for intermediate enthusiasts. We layer foundational concepts with practical examples, expected price ranges, and authentication checkpoints so you can read once and reference repeatedly. If you are completely new, we recommend reading our beginner’s roadmap (/start-here/) alongside this material.
How current is the information in this vintage games guide?
This guide reflects 2026 market conditions, grading standards, and authentication best practices. We periodically refresh content as auction records, grading-service criteria, and counterfeit techniques evolve. The guide’s last-updated timestamp shown by your browser corresponds to our most recent factual review.
What’s the most common mistake collectors make in vintage games?
Buying before learning. The hobby rewards patience: collectors who spend the first 60-90 days reading, attending shows, watching auction results, and asking questions in established communities consistently outperform those who buy aggressively from day one. Education compounds; impulse purchases rarely do.
Where can I get items in vintage games authenticated?
For most categories, established third-party authenticators include PSA, BGS, CGC, and SGC for cards; PCGS and NGC for coins; BBCE for sealed Pokémon and sports wax; AFA for toys; and recognized industry experts or auction-house specialists for watches, autographs, and fine collectibles. Independent verification typically costs $20-$200 and is well worth it for any item over $500. See our /authentication-hub/ for category-specific recommendations.
How do I sell vintage games for the best price?
Match the venue to the value. Items under $100: eBay or Facebook collector groups. Items $100-$1,000: eBay with strong photography and detailed descriptions, or category-specific platforms (StockX, Discogs, Catawiki). Items over $1,000: established auction houses (Heritage, Goldin, Christie’s, Phillips) or vetted dealer consignment. Avoid pawn shops (typical offers: 20-40% of fair value) and unverified buyers offering instant cash.
