Aspects
Commodity money is to be distinguished from
representative money, which is a certificate or token which can be exchanged for the underlying commodity, but only by a formal process. A key feature of commodity money is that the value is directly perceived by its users, who recognize the utility or beauty of the tokens as goods in themselves. Since payment by commodity generally provides a useful good, commodity money is similar to
barter

History

Commodities often come into being in situations where other forms of money are not available or not trusted, and these are social norms.
Various commodities were used in pre-Revolutionary America including
wampum (shell beads),

. They wanted goods such as metal knives and axes. Rather than use a
barter system, the fur traders established the
made beaver (representing a single beaver pelt) as the standard currency, and created a price list for goods:
* 5 pounds of sugar cost 1 beaver pelt
* 2 scissors cost 1 beaver pelt
* 20 fish hooks cost 1 beaver pelt
* 1 pair of shoes cost 1 beaver pelt
* 1 gun cost 12 beaver pelts
Other animal furs were convertible into beaver pelts at a standard rate as well, so this created a viable currency in an economy where precious metals were not valued. However, for convenience, Hudson's Bay post managers exchanged
made beaver coins, which were stamped pieces of copper or brass.

Legal tender issues
Today, the face value of
specie and base-metal coins is set by government fiat, and it is only this value which must be legally accepted as payment for debt, in the jurisdiction of the government which declares the coin to be legal tender. The value of the precious metal in the coin may give it another value, but this varies over time. The value of the metal is subject to bilateral agreement, just as is the case with pure metals or commodities which had not been monetized by any government. As an example,
