The Premium of Sealed Games
Sealed games sit at the top of the collecting hierarchy. A factory-sealed game guarantees that the contents are in their original, untouched state. The scarcity of sealed copies -- most games were purchased to be played -- combined with the certainty of mint-condition contents makes them the most desirable items in any collection. Grading adds another layer of value by professionally verifying the seal's authenticity.
Authenticating Factory Seals
Seal authentication is perhaps the most critical aspect of sealed game grading. Grading experts examine the type of wrap, seal placement, adhesive patterns, and wrap tension to determine if the seal is original. Different manufacturers and eras used different sealing methods -- understanding these historical details is essential. A professional grading service has the expertise to distinguish genuine factory seals from sophisticated reseals.
Seal Grading Criteria
When grading a sealed game, the seal itself receives particular attention. Graders evaluate the tightness and uniformity of the wrap, the condition of any security stickers, the clarity of the cellophane, and any visible damage such as tears, punctures, or loose edges. A perfect seal with no visible flaws contributes significantly to the overall grade, while seal damage will proportionally affect the assessment.
Protecting Your Sealed Investment
Sealed games are particularly vulnerable to environmental damage. The plastic wrap can shrink in heat, crack in cold, and yellow under UV light. Humidity can promote mold growth beneath the seal. Professional encapsulation provides a controlled environment that mitigates all of these risks. For sealed games representing significant value, grading and encapsulation is the most prudent form of long-term protection.
