I established a new personal record today. In one $50 dollar bag of CWR there was $50.01 of copper pennies. Every roll... solid copper + one bonus penny:)
When I picked up the bag from the credit union the teller told me that an old guy had dropped off a bunch of old penny rolls and that most of them were labeled 1973, etc.
Every last penny in every roll was copper. 90% of the rolls were sorted by year.
In the entire bag there was not one zinc, canadian, or wheat.
Sweet! The Copper Gods were smiling down on you! Best I've done is a few solid copper roles here and there from random CWRs. To get 50 bucks worth is amazing. The easiest 33 lbs. of copper ever!
