Beckett Grading Services uses an easy-to-understand 1 to 10-point grading scale, with descending increments of one-half point (for example 10, 9.5, 9, 8.5, etc.). Since you are provided with a detailed report on your card's key attributes, there are no confusing qualifiers to decipher.

Top-graded cards are identifiable at a glance thanks to Beckett Grading Services' premium-colored labels. A gold label on the front of the unique cardholder signifies the highest graded cards (9.5-10). A silver label graces cards graded 8.5 to 9. Cards in all other grades are identified with a distinctive and attractive white label.
