Scarcity value

Scarcity value is the economic factor that increases an item's relative price based more upon its relatively low supply. Whereas the prices of newly manufactured products depends mostly on the cost of production (the cost of inputs used to produce them, which in turn reflects the scarcity of the inputs), the prices of many goods—such as antiques, rare stamps, and those raw materials in high demand—reflects the scarcity of the products themselves.
