When copper traded for an average of $3.30/pound, copper production generated nearly $5 billion for Arizona's economy in 2006 and $5.5 billion in 2007.
Citi encouraged automakers and others to hedge their copper purchases, warning that the price jump could cost unhedged manufacturers an overall $320 billion, equivalent to roughly 0.4% of global GDP.
It has a diameter of 0.955 inch (24.26 mm) and a thickness of 0.069 inch (1.75 mm). Its current version is composed of two layers of cupronickel (75% copper, 25% nickel) clad on a core of pure copper. [2] With the cupronickel layers comprising 1/3 of total weight, the coin's overall composition is therefore 8.33% nickel, 91.67% copper.
