Hi Scalectrix,

to the forum!
As the first 2 coins have been dealt with, here's a bit of info re the rest:
3. 1916 Half Penny - Australian
4. 1916 Penny - Australian
5. 1919 Six Pence - Australian
6. 1946 Half Crown - Great Britain
7. 1959 Shilling - Australian
8. 1886 Three Pence - Great Britain
9. 1948 Six Pence - Australian
As Malissa suggested, it would be best to post photoe in the grading section, and show both sides of the coins.
I'm no expert on grading, but coins 4, 6 & 7 look OK to me. No 8 is not too bad for a coin of it's age.
