Condition & Grading – How to Assess Retro Games and Consoles

Learn how to grade retro games, consoles, and collectibles. Golisto's condition guide covers everything from loose cartridges to sealed collector items.

Condition is everything in retro collecting

The difference between a "Good" and "Very Good" grading can mean 30–50% in resale value. A missing manual can cut a price in half. And a game that looks mint to the untrained eye may be a reproduction that's worth almost nothing.

Golisto's Condition & Grading section gives you a shared language for trading retro items fairly – and confidently.

Golisto's condition grades explained

Sealed / New Old Stock (NOS)

Never opened. Original factory seal intact. The highest possible grade. Commands a significant premium and requires careful verification.

Complete in Box (CIB) – Mint / Near Mint

All components present. Minimal signs of use or storage. No writing, tears, or significant wear.

Complete in Box (CIB) – Good / Very Good

All components present but with visible wear. May include price stickers, shelf wear, or minor fading.

Loose – Mint / Near Mint

Cartridge or disc only. Item itself is in excellent condition with no significant marks or damage.

Loose – Good / Acceptable

Cartridge or disc with visible wear, label damage, or minor writing. Fully functional.

For Parts / Not Working

Item has known faults or is incomplete in a way that affects function. Must be clearly stated in listing.

The factors that move the price

Collectors look beyond whether an item works. Box condition, manual presence, inserts, label quality, case cracks, disc scratches, and plastic yellowing can all change the final value.

Authentication

How to spot a fake or reproduction

Reproduction cartridges can look convincing at first glance, especially on high-value NES, SNES, and Game Boy titles. Use these checks before you trust the listing.

Original cartridge

Correct label

Correct artwork, original screw, and expected PCB markings.

Reproduction

Off-colour label

Off-colour print, Phillips screw, or PCB mismatch.

Label quality

Reproductions often have slightly off colours, different fonts, or missing fine print.

Screw type

Original Nintendo cartridges use proprietary screws. Standard Phillips head screws are a red flag.

PCB markings

If you can open a cartridge safely, compare the circuit board to known originals.

Weight

Some reproduction cartridges are noticeably lighter or heavier than originals.

Price

If a rare title is priced well below market value, reproduction is a serious risk.
