Last week I asserted that coins have never been a form of commodity money; rather they have always been the IOUs of the issuer. Essentially, a gold coin is just the state’s IOU that happens to have been stamped on gold. It is just a “token” of the state’s indebtedness—nothing but a record of that debt. The state must take back its IOU in payments made to itself. “Taxes drive money”—these “money things” are accepted because there are taxes “backing them up”, not because they have embodied gold. As promised, this week I will begin try to dispel the view that coins used to be commodity monies. Next week, we will finish up the discussion.
In this Primer I do not want to go deeply into economic history—we are more interested here with how money “works” today. However, that does not mean that history does not matter, nor should we ignore how our stories about the past affect how we view money today. For example, a common belief (accepted by most economists) is that money first took a commodity form. Our ancient ancestors had markets, but they relied on inconvenient barter until someone had the bright idea of choosing one commodity to act as a medium of exchange. At first it might have been pretty sea shells, but through some sort of evolutionary process, precious metals were chosen as a more efficient money commodity.
Obviously, metal had an intrinsic value—it was desired for other uses. (And if we take a Marxian labor theory of value, we can say metal had a labor value as it had to be mined and refined.) Whatever the case, that intrinsic value imparted value to coined metal. This helped to prevent inflation—that is, decline in the purchasing power of the metal coin in terms of other commodities—since the coin could always be melted and sold as bullion. There are then all sorts of stories about how government debased the value of the coins (by reducing precious metal content), causing inflation..
