Sealed / New Old Stock (NOS)
Never opened. Original factory seal intact. The highest possible grade. Commands a significant premium and requires careful verification.

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

Reproduction
Off-colour print, Phillips screw, or PCB mismatch.
Reproductions often have slightly off colours, different fonts, or missing fine print.
Original Nintendo cartridges use proprietary screws. Standard Phillips head screws are a red flag.
If you can open a cartridge safely, compare the circuit board to known originals.
Some reproduction cartridges are noticeably lighter or heavier than originals.
If a rare title is priced well below market value, reproduction is a serious risk.
