Durability

Durability is the ability of a good to retain its original state overtime. In order to be considered durable, a good must be difficult to damage or alter. Durability is a necessary property of money because the money must be able to sustain its value over time.

For this reason, beans, shells, livestock, or other objects previously used as money did not succeed overtime because they were not durable. Likewise, gold emerged over other metals due to its durability: gold neither rusts, corrodes, or tarnishes.
