I'm actually having a hard time understanding your coin distribution. I believe it's real and all, it just doesn't make sense.
My problem is that if you take all of your coins from change and immediately deposit them in these bottles, you should have way more pennies than anything else, just slightly fewer quarters than pennies, maybe half the number of quarters in dimes, and very few nickels. (Unless you only pay in cash for very few, very specific things)
Do you often keep some change in your pockets before depositing it? If so, do you spend some of it before you deposit it?
My logic for the coin numbers is as follows: You'll always receive between 0-3 quarters, 0-2 dimes (because 3 dimes is more simply 1 quarter and 1 nickel), 0-1 nickels (because 2 nickels is a dime), and 0-4 pennies (assuming, of course, that the cash register has enough coins to make proper change). So, for example, assuming a random distribution of change within those parameters you should have a ratio of 1.5

0.5:2 (quarters:dimes:nickels

ennies) which is certainly very far from what your coin collection actually exhibits.
Very strange...
