The value of a trading card depends on a combination of popularity, scarcity, and condition. Older cards are usually the most sought after. Newer cards haven't appreciated as much in value due to mass production, despite the fact that manufacturers have used limited editions and smaller print runs to boost value. Cards do not have a true monetary value attached to them anyway. The actual price of the card is only what another will pay for it. For that reason you will not find any grading or values on Cardboard Highway - just information. Collecting cards should be fun and as stress free as possible.
