Answer:
The rank would be:
1. Tow ounces of gold - because gold is a very liquid asset that can easily substitute money. With the gold, I could obtain anything I wanted, as long as the gold is enough.
2. Two sacks of grain - food is the most important good, and the first that has to be supplied for.
3. One pound of salt - salt is also a valuable good that can be used to preserve food, or even to trade for other goods, as a commodity substitute for money (just like gold but less commonly so).
4. A bundle of wool - this can be used to make garments that are also very important for daily life.
5. Several hides of leather - because I would be trading cattle, l am likely a cattle raiser, and leather should be readily available for me.
