Aug 1947: Clarence Ellsworth had been saving pennies by dropping them through a crack in his attic floor. Finally, when the number of pennies reached 1,672, the weight of the pennies broke through the ceiling and landed in his living room.
This raises the question: how much did 1,672 pennies weigh?
According to Wikipedia, pennies issued before 1982 each weighed 3.11 grams since they were made from 95% copper. After 1982, the U.S. Mint substituted a copper-plated zinc penny that weighed less.
3.11 times 1,672 comes out to 5200 grams (rounding up) — or approximately eleven and-a-half pounds.
I'm surprised that was enough to break his ceiling. Perhaps there were other issues, such as water damage, that contributed to the break.
According to an online inflation calculator, $16.72 in 1947 money would be worth $234.18 today. And the repairs would have cost approximately $175 (in today's money).
