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.
Autographed programs and ticket stubs have their greatest value if some historical moment occurred at the event, or if it is an event considered important (like a World Series or Super Bowl). Who signed the item enhances its value as well. To preserve the value keep these items in protective sleeves.
Autographed photos can be very desirable especially if it is considered scare. The most common sign is 8×10. For resale if it is personalized it will diminish its value. Also having authentication from a reliable source will help for resale purpose.
Autographed postcards can be fun to collect. The best way is to send a stamped self-addressed one to an athlete, and ask that he or she sign it on the cover and send it back by return mail. For added value, ask them to include a brief inscription on the back of the postcard.
Lithographs, posters, and prints have a curious value fluctuation. Limited edition and numbered prints that are autographed are of greater value, than those that are signed and have been mass produced. For the greatest return, frame the items and protect them from sunlight.
