Knowledge Hub
Learn how to accurately grade condition to maximize value and build buyer trust.
Condition is the single most important factor in determining a collectible's value. A mint-condition cartridge can be worth ten times more than a heavily worn copy of the same title. Understanding grading terminology — loose, CIB, sealed, near-mint — is essential for both buyers and sellers.
Professional grading services like WATA and VGA provide standardized assessments, but learning to self-assess condition saves time and helps you price items accurately. On Golisto, honest condition descriptions build trust and lead to smoother transactions.
