Auction houses are taking notice of the vintage game industry, and game-grading firms are giving certification for the developing sector.
An unopened edition of 1985’s “Super Mario Bros” set the world record when it bought for $2 million on the collectors’ site Rally in early August. Professional grading and classification have changed the landscape, makes it much easier for customers to evaluate the quality of their transactions.
