According to the interweb, a US dime is 0.08 oz.
2 million dimes = 10,000 lbs of dimes
Yup. 1/4 lb per $5.00 roll, or 5 tons.
40,000 rolls. No idea how those are transported, likely in boxes. I found a pic of a dime box which holds $250; that makes 800 boxes.
Based on the dimensions I found, that would fit a space 5 feet across, 8 feet deep and just under 3 feet tall.
Smaller and heavier package than I figured off the top of my head.
Can’t help but wonder how they plan on moving the cash...
