What does 5 gallons of pennies look like?
See nearby picture. Never try rolling a full five gallon jug of pennies. The sides are not as strong as the bottom.
It took the better part of two decades to acquire this many pennies. As you can see the jug broke and created a very big mess. Each gallon of pennies is approximately $50 [total was a little more than $250]. The credit union had an industrial coin counter. It probably took less than thirty minutes to count them all.
