Commodity money Commodity money Commodity money is money whose value comes from a commodity of which it is made. Commodity money consists of objects that have value in themselves (intrinsic value) as well as value in their use as money. Examples of commodities that have been used as mediums of exchange include gold, silver, copper, salt, peppercorns, tea, large stones (such as Rai stones), decorated belts, shells, alcohol, cigarettes, cannabis, silk, candy, nails, cocoa beans, cowries and barley. These items were sometimes used in a metric of perceived value in conjunction to one another, in various commodity valuation or price system economies.
Aurum Geyser Aurum Geyser Aurum Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States, on Geyser Hill. Aurum can, at times, be very predictable. Other times it can be very erratic. Observations have led to the theory that Aurum's activity is linked to the meadow behind the geyser. When the meadow is wet, activity is regular with 3 to 4 hours between eruptions. When the meadow dries in late summer and early fall, the interval becomes less predictable ranging from 4 to 7 hours. Aurum also participates in the weekly Geyser Hill wave. It
