New South Wales is a state in Australia of which I do have a 20 cent and 50 cent coins. Is this what you are after or is there a country of the same name I havent heard of
I would've assumed he was talking about the Holey Dollars and Dumps, the only coinage issued in the name of "New South Wales" as a separate country. For myself, the trade tokens issued my NSW merchants (and listed in the 1800's Krause) fill that particular gap in my OFEC list nicely.
And if you want to be pedantic, the "Sydney Mint" sovereigns and halves could quite justifiably be called "New South Wales" coins, as Sydney was the capital of NSW colony at the time.
Oh, yes - almost forgot. I've got a New Hebrides 20 francs 1967 that I've been trying to get rid of for a while now... nobody wants it. The poor thing's got a partial drill hole / mount mark on both sides. I'm left wondering what bored local would attempt to drill a hole through a coin made of pure nickel...
