Novelty items from the music and entertainment industry have mixed levels of interest. Complete lunch boxes promoting certain iconic characters are in great demand, as are vintage music memorabilia. Popularity, condition, and scarcity are important in determining value. One way to get an idea as to the desirability of a novelty is to visit auction sites looking for comparable items. Monitoring the bidding for them is a good way to tell is an object is worth collecting.
The collectability of concert memorabilia rests on a number of factors. The historical significance of the show (the first or last performance), what the memorabilia is (equipment, instruments, posters, etc.) and the availability of similar items. Autographed items are more desirable than non-autographed items, and original printed products are better than reproductions.
Clothing and other apparel associated with greats in the music industry can have mixed appeal. The degree of fame or notoriety of the individual in question provides the greatest boost to value. Autographed items are also highly desired. Apparel from certain landmark events, concerts, or recording sessions will generate interest, especially if documents that validate the item accompany it.
Almost any item associated with a movie can attract a collector. The difficulty lies in trying to discover what items will have the greatest following. One way to determine demand is to place the item on an auction site and gauge the response. If the reaction is notable, then the item(s) have an audience and are probably worth collecting. If the response is minimal, collecting it should be abandoned, or hold onto the item and try auctioning it at a later time.
Movie scripts are the most collectable if they contain the revisions of the writer(s) or directors. The script from a well-known film is desirable, but its value is at the lower end of the spectrum. Scripts autographed by the movie’s key personnel enhance its value.
