Nice coins - Love the way they have aged.
From the photos !
1910 - Strength in the star, emu feathers, grass and "ADVANCE AUSTRALIA" indicate much better than the 1912. Obverse shows a hint of pearls 7 & 8 (in the photo).
1912 - its a nice VF+ from the photos and a bit of a problem with the rim at 10-11 o'clock reverse.
Thanks for posting the pics.
