Is it worth saving pre-1982 pennies?
I have a collection of pennies, some of them are pre-1982 pennies. I'm wondering if it's worth keeping them or if I should just spend them. Are pre-1982 pennies worth saving?
Why do pre-1982 pennies weigh more?
I have some pennies that were minted before 1982, and I noticed that they seem to weigh more than the pennies minted after that year. I'm curious to know why there's a difference in weight. Could it be due to a change in the composition of the coin, or some other reason?
