1914-D Lincoln Cent / Money Jar Contest!

Fun contest, thank you

Congratulations, Kena, on a job well done!

I am curious about how everyone came up with their guess. Were they random or a serious attempt at calculation? I went with the serious attempt on this one.

First, using the diameter of the clearest nickel, I determined the diameter and height of the jar, and doing my best to account for the perspective of the camera and irregularities of shape. I came up 1022 ml. Within error, this looks like a 1 liter volume bottle. The bottle looks like about 85% full. From these numbers, I went to the bank and got $100 in change in a mix of nickels, dimes, and quarters. visually, the jar looks extra heavy with nickles, so I used more of those in my mix. There are no cents visible, so none were added. I added a few halves as that seemed reasonable for a change jar. The water bottle I used was a little less in diameter that the contest one, so I added $5 to my estimate because the larger diameter will pack a little more efficiently. In the end, I underestimate the fraction of quarters and had way too many nickles I was close on dimes.

But, not all was lost I got a 1940 nickel in one of the bank rolls. All the dime rolls were 100% BU 2016, so I kept one roll. Best of all, I had fun

Just a wild guess on my part.

I let everyone else come up with the educated guesses. These I sorted in a spreadsheet and selected the midpoint between the two having the greatest spread. This gave me more "chances" than anybody (except at the extremes) but obviously failed miserably! Haha, it was fun!!

Wild guess on my part ... great contest indeed.

Many thanks to the host turingmach
