Many years ago, (1968 to be exact), I completed an Australian sovereign and half sovereign type set that included an Adelaide Pound, all Australian minted.
It was auctioned just before we married to raise deposit money for our first house which we bought in 1976.

They just HAD to be all Sydney Mint coins, because that is the city in which I live.
The collection was sold, along with about 90 Roman coins, which included two gold aureii of Claudius and Hadrian, and a solidus of Constantius 11, and
a pre decimal Australian type set in bronze and silver, where each type was represented by the rarest date except for the 1930 penny, a '25 penny was included instead.
I bought the Adelaide Pound for myself for my 21st birthday, with accumulated money from my 21st, and saved money. I paid $250 for it at the time.
I reasoned that you can't put a roof over your head with a stack of rare coins!
The house cost $35,000 in 1976, and would now be valued at about $525,000.
