No expert on Notes but do have similar hoard of $1 & $2 myself.Unless they are Unc. they struggle to make double face.Those that have 'Commonwealth of Australia' instead of
just 'Áustralia' are worth slightly more.
The 1988 $10 can be worth anything from $20-$50,more with certain serials,Google is your Friend.
My BiL collected the plastic $10 from the Business he ran and has over 100 of them so there are plenty around.
