Dumped it out in the bin this morning on the way to work. I'll post the total and the coin breakdown later tonight.
My guess was off by $7.

Ok, here's the results, spoilered in case anyone else wants to guess.

The grand total was 97.46. There were 61 quarters, 444 nickels, 406 dimes, and 1841 pennies.
I'd calculated the weight of 4 quarters, 20 nickels, 10 dimes and 100 pennies, and divided that into the total weight, then multiplied by 4, and it came out to $89+, so I rounded my guess up to $90.

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...

I don't use cash much anymore. Groceries I usually use the self-checkout and that's easier with the debit card. Laundry uses the debit card. If I eat out with friends stuff gets rounded up to the next dollar when we divvy up the bill, etc. And I'm not anal about counting out change usually -- I hate those people that slow up the checkout line
If I do have change in my pocket, I will often throw in some change if the total bill is a little over a dollar amount -- eg, if the bill is $5.10, I'll pay $6.25 to avoid the walking around with all the excess change. Change rarely carried over from day to day, though -- it got dumped in the jars at night.
For a good chunk of the time that that batch was accumulating, I was grabbing coffee and a bagel at the same coffee shop most mornings on the way to work, and that was $3.81, so maybe thats where the skew comes from.

Since I guess I came the closest, I'll share my methodology.
It's been my experience that you guy about twice as many dimes as quarters, four times as many nickels, and eight times as many pennies. That was an estimate using what change I had, which I'd guess to be about forty dollars worth. IMO, the estimate for dimes especially was high, but quarters was also high.
18.8 pounds is about 8500 grams. A penny is 2.5g, a nickel is 5.0g. Dimes and quarters are a bit off, but not so much as to make an estimate 2.5g and 5.0g, respectively, invalid.
From there, it's a simple calculation and summation... figure out the grams each group should be (8x+4x+2x+1x), divide by the mass, mulitply by the denominartion.
