Less Tinkle in U.S. Change?

I dropped some American coins on the desk the other day, and was surprised at the almost nonmetallic sound they made.  It made me wonder what the intrinsic metal value of U.S. coins is these days.  As you peruse the following table from Coinflation.com, remember that the intrinsic value of paper money is zero, and that Canada is abolishing the penny because it is too expensive to make:

United States Circulating Coinage Intrinsic Value Table




This table does not reflect U.S. Mint production costs, but the pure base metal value that composes the coin. Calculations are based on coin weight, metal composition, and base metal prices. The "Metal % of Denomination" column represents the percentage of metal that comprises the denomination's purchasing power. A coin that is over 100% in this category has more base metal value than purchasing power.

* The U.S. Mint issued both compositions in 1982; they can be differentiated by weight (3.11 g copper, 2.5 g zinc). The 1943 steel cent is not included in the table above. Also, a tin alloy is used in one cent pieces from 1864 until 1962, but that value isn't significant enough to calculate.
