Want to know if Wheat (grain) would be a good currency?

Go ahead. If your idea has merit people will use it. That being said you need to do so privately, passing a law to force people to use money you like is wrong.

Even Ron Paul is is promotion of a silver currency did not want it to be "legal tender" but instead he simply wanted to remove legal tender laws.

It would certainly bolster the fiber of our economy.

Rothbard - (From "The Case Against the Fed)

Why gold and silver? (And to a lesser extent, copper, when the other two were unavailable.) Because gold and silver are superior in various "moneyish" qualities—quali-ties that a good needs to have to be selected by the market as money. Gold and silver were highly valuable in themselves,for their beauty; their supply was limited enough to have a roughly stable value, but not so scarce that they could not readily be parcelled out for use (platinum would fit into the latter category); they were in wide demand, and were easily portable; they were highly divisible, as they could be sliced into small pieces and keep a pro rata a share of their value; they could be easily made homogeneous, so that one ounce would look like another; and they were highly dura-ble, thus preserving a store of value into the indefinite future. (Mixed with a small amount of alloy, gold coins have literally been able to last for thousands of years.) Outside the hermetic prisoner-of-war camp environment, cigarettes would have done badly as money because they are too easily manufac-tured; in the outside world, the supply of cigarettes would have multiplied rapidly and its value diminished nearly to zero. (Another problem of cigarettes as money is their lack of durability.)

Every good on the market exchanges in terms of relevant quantitative units: we trade in ''bushels" of wheat; "packs"of 20 cigarettes; "a pair" of shoelaces; one TV set; etc. These units boil down to number, weight, or volume. Metals invari-ably trade and therefore are priced in terms of weight: tons,pounds, ounces, etc. And so moneys have generally been traded in units of weight, in whatever language used in that society. Accordingly, every modern currency unit originated as a unit of weight of gold or silver. Why is the British currency unit called "the pound sterling?" Because originally, in the Middle Ages, that's precisely what it
was: a pound weight of silver. The "dollar" began in sixteenth-century Bohemia, as a well-liked and widely circulated one-ounce silver coinminted by the Count of Schlick, who lived in Joachimsthal.They became known as Joachimsthalers, or Schlichtenthal-ers, and human nature being what it is, they were soon popu-larly abbreviated as "thalers," later to become "dollars" inSpain. When the United States was founded, we shifted from the British pound currency to the dollar, defining the dollar as approximately 1 /20 of a gold ounce, or 0.8 silver ounces.

It is not that easy to store wheat. Takes quite a facility. Plus it is very bulky.

have been used for barter and trade for thousands of years.

I think this would be a very poor choice. One year the crop might be abundant, inflating the supply; the next year there might be a crop failure and a serious deflation of the supply. Think what this would do to make prices of things unstable.

Look at the history of money and the characteristics that made gold and silver the premier choices; durability, relative scarcity, expensive to expand supply, easy divisibility, high value relative to weight. Wheat fails on several of these criteria.

This is a must listen if you haven't heard it before. Great way to introduce people to our fraudulent monetary system.
