What is the difference between fads and collectibles?

Answer 1

A collectible is an object that has value because people want to collect it, or because someone thinks people will want to collect it in the future. When people collect something they do that not to use the item for its intended function, but to create what amounts to a private museum.

A fad is a style, process, or object when becomes very popular during a relatively short period of time, then quickly becomes commonplace or uninteresting to most people. some fads involve objects that are thought to be future collectibles, but if it is truly a fad, the value and collectibility will not be realized.
