I went back to North Dakota this week and my daughter-in-law said at someone was turning in pennies and wanted to know if wanted them. I said yes and one 50 dollar bag was all copper and the second bag had less than 5 dollars of zinc. This lady has 10-ten gallons cream cans full of pennies she is bringing in. I quess they are looking for wheats and that all. I left her more money to get more.
