Text: Today, like the currency of most nations, the dollar is fiat money, unbacked by any physical asset. A holder of a federal reserve note has no right to demand an asset such as gold or silver from the government in exchange for a note. Consequently, some proponents of the intrinsic theory of value believe that the near-zero marginal cost of production of the current fiat dollar detracts from its attractiveness as a medium of exchange and store of value because a fiat currency without a marginal cost of production is easier to debase via overproduction and the subsequent inflation of the money supply.

Text: Wrought iron is an iron alloy with a very low carbon (less than 0.08%) content in contrast to cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which gives it a ''grain'' resembling wood that is visible when it is etched or bent to the point of failure. Wrought iron is tough, malleable, ductile, corrosion-resistant and easily welded. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name wrought because it was hammered, rolled or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild or low carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching.
