Scriffles: This Australian Dollar note's worth more than a dollar.

In a big clean up of my home I found a box full of old cards that I'd been sent as a child.
In one from my grandma I found this note which no longer in circulation.
It was generous of my grandma who wasn't well off to post me a little something.
I don't know what year I received it unfortunately.
But if was before 1984 when this note was replaced with a coin.
So I Googled what an Australian One Dollar Note is worth and found it could be anything from $30 to $3000.
Knowing my luck it's the first and this note is not in mint "crisp" uncirculated condition.
What it's worth
It's crinkled - though it's been stored flat - and torn and folded and bent a little.
Just like me. :)
