A collector's item is an object or item of any kind that has become valuable -- often unexpectedly. Over the years, a large number of incidents have resulted in certain objects related to those incidents becoming very desirable and valuable. The objects, which may have been common everyday items when they were originally produced, have since gone on to become rare and valuable, and have sometimes been sold to collectors for large sums of money.
Some examples of collector's items are:
Various manufacturers have occasionally attempted to deliberately create a collector's market for their products, in the hope that they will increase in valuable and become true collector's items (and thus make a profit for the manufacturer). A few of these attempts to create collector's items have been successful, but most "collector's items" created to artificially inflate the collector's market have ended up as worthless or near-worthless in value.
