Different grading systems, such as PSA, Beckett (BGS), and SGC, significantly influence the value of trading cards by providing standardized assessments of a card’s condition and authenticity. A card graded as "Gem Mint 10" by a reputable company often commands a much higher price than a similar, ungraded card or one graded by a lesser-known service. Variations in grading criteria, reputation, and consistency between companies can cause fluctuations in demand and market value, making top-graded cards from the most trusted services especially desirable to collectors. This interplay transforms grading into both an art and science, where every scored corner and surface flaw shapes the card's story and worth.
