As a new collector there is a lot to learn about memorabilia collecting but there is also some risk.
GAI and eBay are here to help lessen that risk and make Your collecting experience safe and fun.
As with all collectibles, condition is a key factor in determining value.
Trading cards are no different. In fact, trading cards may be more dependent upon expert analysis of condition,
simply because of the breadth and nuances of the certified market.
To better understand why dealers and collectors have turned to third party grading, first we have to understand the need for grading.
Several factors, including rarity, demand and condition, are key to determining the value of your trading cards. Ultimately, condition equals price.
The process of grading at Global Authentication (GAI) reflects years of refinements.
