As a stunt to publicise the 99.999% pure one-ounce Canadian Gold Maple Leaf series, in 2007 the Royal Canadian Mint made a 100 kg 99.999% gold coin, with a face value of $1 million, and now manufactures them to order, but at a substantial premium over the market value of the gold. [3] [4]

This leads to the possibility of smelters taking coins and melting them down for the scrap value of the metal. Pre-1992 British pennies were made of 97% copper; but as of 2008, based on the price of copper, the value of a penny from this period is 1.5 new-pence. Modern British pennies are now made of copper-plated steel.
The word shekel is based on the triliteral Proto-Semitic root ṯql, cognate to the Akkadian šiqlu or siqlu, a unit of weight equivalent to the Sumerian gin2. [1] Use of the word was first attested in c. 2150 BC under the reign of Naram-Sin of Akkad, and later in c. 1700 BC in the Code of Hammurabi.
