Trading Card Grading
Trading cards of all genres, both sports and non-sports, can be submitted to PSA. Once the card graders have determined the card to be genuine, they are then asked to determine whether or not the card shows evidence of doctoring. Doctoring is best described as the attempt to enhance the condition of a card by altering the condition, such as re-coloring or trimming.
Finally, assuming the card passes the first two stages, the experts are asked to grade the condition of the card on a scale of 1-10 with 10 being best. Once the grade is rendered, the card is then placed in a tamper-evident case which contains all the pertinent information on the label, including the unique certification number. A similar procedure is also used for collectible coins and pins.
