Is it true that copper- pennies are worth more than one cent now?
Something I read in more than one place, says if the dollar collapses and the government devalues it into new dollar bills, that they would recall old dollar bills but not change. Ten old dollars becomes one new dollar; however a quarter worth old $0.25 in change becomes new $0.25, worth $2.50 in old dollars - you make money on change. It's not worth the governments time and labor to recall change during a changeover. Happened before, will happen again.
The wife has tens of thousands of coins around, it's unwieldy and heavy to move around and a hassle! And yes, 1982 and earlier copper pennies are worth more. The later ones are mostly zinc, toss them back into circulation.
