Herkimer, Copper cents weight 3.11 grams each give or take, depending on it's original weight within mint tolerance, and how much circulation it's seen.
there's about 145 copper cents per pound.
and for Zinc cents it's approx. 180 cents per pound because they are lighter to start with.
A bag of 5 pounds would contain 725 copper cents approximately, probably a little more because of the worn coins, and that's IF they weigh it legitimately when packaging and it's not underweight
These guys got a marketing name for everything "Lakeland Bankers Hoard" hahaha A simple internet search shows you just how famous that "hoard" was! Nada.
