For sale is 5000 95% copper pennies all dated pre 1982.
Unlike most of the other lots for sale, mine doesn't have any 1982's. 
You are getting your money's worth. Do you think the other sellers are
weighing each 1982 to make sure they are 95% copper? I doubt it.
That's a lot of extra work for them. Most of those lots will have 100's of 1982's. 
I looked thru these by hand just searching dates, nothing extra. 
I've added a few extra copper pennies to each bag in case a few
zinc's fell in (I'm human, not perfect).
These pennies are getting harder and harder to find, so stock up while you can.

Copper price as of 5-21-24 is $4.87 a pound.
Each penny is worth $.0322 copper melt value.
     5000 pennies x .0322 = $161.00 per bag.
