 SiN is correct, it's a bit more than 300 pennies. Try by two orders of magnitude. I'm guessing over 30,000 pennies!
Weighing the jug and pennies would be a good method, but the jug is glass and I don't know how much it weights alone (I guess I'd have to empty it).
Water displacement is another good idea, but then I'd have over 30,000 wet pennies
