1 U.S. cent is 3/4'" in diameter.
16 cents = 12"
16 x 16 = 256 copper cents per square foot (1 layer). Their weight is 1.765 lb.
A cent is .060" thick.
12" ÷ .060" = 200. 200 layers x 1.7 lb. = 353 lbs.
It appears that website rounded up the thickness of the cent to .0625" (1/16"). That gave them 192 layers, giving them 49152 copper cents ($491.52). That gives a weight of 337 lbs.

Remember that the new large Flat Rate Boxes are under 1/2 of a cubic foot. The traditional Flat Rate Boxes are 1/3 of a cubic foot.
If you look at the pic provided and calculate the weight of the cents shown (using copper cents = 3.1 grams each) you get: 49,152 cents X 3.1g = 152,371 grams divided by 28.4 grams/ounce(adv.) = 5,365 ounces divided by 16 ounces/pound(adv.) = 335 pounds.

A large USPS flat rate box stuffed full of wheaties is only 75 pounds. If you don't believe me, BiggFredd will tell ya, right BF? Actually, a hair under 70#. However, that box is 8.5*11*5.5", for a total of 514.25"³, while a '³ is 1728, or 3.36 times as big. So 70#*3.36=235#, plus I'm sure they're filling the box edge to edge (no canvas bags), and perhaps not counting off for the space where coins don't exactly meet. It's all in perception. Most people have no idea how big a cubic foot is (the large priority boxes are less than ½'³.) I had a foot high stack of 14" aluminum HDs with 6" holes, and they weighed 135#. And a sheet of ¼" plate glass about 6' on a side weighs several hundred pounds. One time I drank some barium for an x-ray. darn near dropped the cup. The size of a small styrofoam cup, but weighed as much as a couple of those big "oil cans" of Foster's. |

My dads got 3 water cooler jugs full of cents, Id hate to try to left even one of them. Again, people don't really understand specific gravities (density). Copper is a RCH under 9. So a 5 gallon jug of water is around 40#, and when you fill that glass jug with cents, that jumps to 360#. No wonder the bottom falls out when you go to move it. |

To further Dave2095's comment on water cooler bottles, I went to an auction last weekend and bought a glass water cooler jug full of cents with some nickels, dimes and quarters. 90%+ were cents. There has to be at least 2 cubic feet of coins in it. I am 55 with inflammatory arthritis, stand 5'8" and weigh 198 lbs and my wife is 5'2" and weighs about 125 lbs. I tell you this because we were able to pick it up and put it in the truck. After emptying about 25% of the bottle, I could pick it up myself. If I had to guess, the bottle full was about 150 lbs.

With all due respect, I doubt it was anywhere near 2'³. Go measure it.
I have lifted huge weights (like the back of a car), and there's no way I could lift that much. BTW, I'm 5'19" and have a 56" chest.

That would have to be one massive water cooler as 1 cubic foot will hold about 7.5 gallons of water.

A little off topic, but roughly how much did that cost to purchase? I have never seen a 5 gallon water bottle for sale that was full of coins. Did you find anything good? |

To answer the questions, yes, the wife was the best find  , and I paid 285 plus a 10% buyers premium for it. Have not found anything special, yet. Running about 8% Wheats with the oldest to this point being a 1929. Did find a 1905 dime in about G-8. At the rate that it is going, I will break even and gotten a free water bottle.  I assumed that it was 5 Gal as it looks about the same size a a 5 gal pail. There is no volume scale on it so I will go home tonight, fill it up, and report my findings. Jim |

Just for fun, I'm guessing 2.5-3 gallon.
