text: The Copper Dollar (sold for 1 U.S. Dollar) as with all rounds issued by Liberty Services is promoted as hard money, however based on London Metal Exchange prices of Copper and Zinc (at $7,980 and $2,958.50 per tonne on 2007-10-17 respectively), it can be calculated that the actual value of one avoirdupois ounce of copper in a Liberty Copper Dollar round is worth just over 22 cents, whereas after separation, the copper and zinc content of 100 U.S. pennies is worth over 74 cents.
