Portability - Money is small and transportable. Imagine using certain types of commodity money. What if Cows where accepted as commodity money. Divisibility - Money can be broken down into smaller or larger units of measure to make transactions easier. Durability - Money lasts.
Specie lasts forever and even paper currency is pretty durable.
In class I ripped a twenty dollar bill in half once and then taped it back together. Eventually even an un dismembered cow would die, rot and stink. Not too durable. Stability of Value - Money, despite the influences of inflation and deflation remains fairly stable in value. Money is not subjected to the natural forces of weather as much early commodity was.
