You're kinda right. I messed up based on someone's decimal place screw up when I researched how much a penny weighs. Now that I have fixed the screw up, I calculated that approximately 182 pennies will weigh 1 pound, making it so that $800 worth of pennies would actually weigh approximately 439.5604395604396 pounds or 0.2197802197802198 tons. This is all based on information claiming that a penny weighs 2.5 grams or 0.088 ounces. The original mess up was due to someone claim 0.88 instead of 0.088.
