 Usually in a fiat money the value drops if the coin is converted to metal, but in a few cases the value of metals in fiat moneys have been allowed to rise to values larger than the face value of the coin.In India, for example fiat Rupees disappeared from the market after 2007 when their content of stainless steel became larger than the fiat or face value of the coins.In the US, the metal in pennies (97.5% zinc since 1982, 95% copper in 1982 and before) and nickels (75% copper, 25% nickel) has a value close to, and sometimes exceeding, the fiat face value of the coin.
