Yokozuna's 1 0 0 0 Th Post Contest Guess And Win A T-Shirt!

Of course the Day 2 clue was helpful!

The scale said 1500 grams. If the jar is glass, maybe that counts for 500 grams. SO, if there are 1,000 grams of coins, that would be:

$4 of post 1982 pennies ... or ...

$10 of nickels ... or ...

$44 of dimes or quarters

So, if a third of the mass of coins is pennies, a third is nickels, and a third is dimes and quarters, we are talkin' in the ballpark of 19 bucks. If a higher proportion is pennies, the amount will be lower.
Of course, that is a whole bunch of assumptions, any of which could be off ... but makes it no surprise the amount is over $10.

I'll guess $15.73

$11.25

$14.92

$19.02
