Basketball
Basketball trading cards are slowly growing in value. The primary determinants are the player depicted, what stage of the career the card is from (rookie cards are the most valuable), the condition of the card (it must be in mint or excellent condition), and whether or not the player is in the Hall of Fame. If any of these factors are missing, the value is lowered. Place any card in a protective sleeve to keep it from being damaged. The cards should not be autographed.
