The copper alloy pennies are about 2.6 grams and ring nicely when
dropped (like a bell). The copper-coated zinc pennies are 3.1 grams
and land with a dull thunk when dropped.
Curiously, you can't tell if a 1982 penny is copper alloy or coated
zinc without weighing it on a sensitive balance, or dropping it and
listening for the ring or thunk.
Zinc and Nickel prices have risen, too, although not quite as
dramatically as copper.
I wonder if we'll see the return of the Zinc-plated Steel pennies
(like from 1943).
