I was given a 'golden' opportunity to learn a bit about your country currency yesterday ...
My local USA bank had two Australian dollars in the reject bin of it's coin counting machine ... which I of course accepted gratis with a sincere interest to attempt some knowledge of your coins through personal research.
Apologize if I have all the following wrong ... corrections gladly accepted.
1995 Mob of Roos Dollar
In the USA I would grade this coin at VF25/VF30 (Sheldon). Have read enough of your Aussie standards to realize that is not consistent with your grades.
This coin is horribly beat up on the surfaces with bag hits everywhere ... weight is 9.02 grams.
I was surprised to examine the coin edge ... impressed with the 7 flats mixed evenly amongst the reeded edge. Nice touch by the Aussie Mint.

My limited research tells me there were 23 total variety/mm to collect of your 1995 dollar ... geepers!
Alloy is what you call AL-BR ... 92% copper, 6% aluminum and 2% nickel.
Mintage of 5,792,000 ... the 'fun fact' that I believe I found is that the 1995
Mob of Roos was actually a mistake ... the initial release was not intended and subsequent strikes were released to avoid an embarrassing moment at the Aussie Mint.
2001 Centenary of the Federation
In the USA I would grade this coin high AU ... perhaps AU55 (Sheldon) .. in hand it is much cleaner than my poor photos show.
Same comments as your 1995 dollar mentioned above ... reeded edge with 7 flats ... AL-BR alloy ... weight is 8.97 grams.
Believe I learned there were 14 total 2001 Aussie Dollars by date/mm ... wow! Mintage of this example was 27.9 million.
Fascinated by the Aussie 'medal orientation' for your coins ... was a bit surprised to discover this 2001 Dollar has approximately 10 degrees die rotation ...
A bit more research revealed that it is not uncommon for this coin to exhibit a die rotation ... fun that I found it here in the USA.
Close with this ... as am amateur numismatist I truly enjoyed my first in-hand look at your currency ...
Hoping I did not get it all wrong.
