The value in game equipment from NCAA sporting events rests solely in who has signed it, or in the historical significance of the event. This is because of the number of collegiate sports, the number of colleges and universities, and the different tiers of the NCAA.
Basketballs, uniforms, and other equipment used in the various professional basketball leagues are difficult to come by. Simply possessing one, though, is not enough. It must somehow be identified as a ball from an event. Autographs and dates help, especially if signed by participants. The final score and what happened in the game increase its value, especially if the game had some historical significance.
Baseballs have a fluctuating value because they are among the most common pieces of equipment used in game settings, what with batting practice, foul balls, and such. If the ball comes from a game of some historical significance, its value increases. If it is signed and dated by players from that event, the value rises. If it has individual significance, a signed ball carries the greatest value.
Like other types of game equipment, the value of pucks and sticks rests on who used the equipment, what happened in the game in which it was used, and if it was used in a game. Broken items diminish in value, but usable, though damaged items are sought by collectors.
An autographed glove, whether golf, baseball, football, soccer, or hockey, is of great interest to collectors, especially if it has game experience. The value increases if the signer is famous, or accomplished a milestone or record while it was being worn.
Autographed magazines carry some interest. The greatest value is for those autographed by the athlete on the cover. After that, if a main article in the publication is about the signed, the interest will be high. Keep it in a protective sleeve to prevent damage and deterioration.
