This was among about 20kg of assorted pennies I came across. How uncommon is it?

A couple of questions - what can I do with 20kg of otherwise unremarkable pennies? I can sell it for the copper but would rather give it to someone who wants them.
I also have a still-wrapped bolt of AUD$1.00 coins, purchased on their first day of issue in 1984. Is it worth more than face value?
I log on only during weekends, if I don't reply immediately to anyone's post that's why.
