I would have been more than happy to pay $US61.
The '42 Melbourne (no mm) reverse suggests that it may be a better than average coin.
I also understand why this set was so cheap, because it was sold in the US market - it would have cost multiples more, had it been sold in Australia.
I have sold rare
US coins in Australia at very low prices, such as a 1923S Quarter VF30 for $50, but that was about 30 years ago.
