A double your money investment
I curiously searched the internet for info on copper prices wondering what pennies are worth if you scrapped them out.
I find out 1000 pennies ($10 worth) weighs 6.25 lbs. and are 88% copper resulting in 5.5 lbs of copper. Copper spot price today is $4.28 per lb. which comes out to $23.54 for the 5.5 lbs of copper in the pennies you bought for $10.
And who knows the scrap yard may give you something for the 12% zinc
Here is my plan... Buy a 30 ton dump truck for $100K, fill it with pennies, haul them to the scrap yard and make $712K profit and make a planter out of the truck.
