Went to Perth Mint today wanting a 100 oz bar and was told sorry None left..No 10 oz bars and no 20 0z bars so I had to settle on the last and only 50 oz bar. Asked when I could buy more of any size. I was told there was a 1-2 month wait on the 10 oz and 20 oz. and lucky dip on anything higher. I have been accumulating since A$17 oz and hope you got yours. They have plenty of 1 oz coins at a premium but the buy back price is the same for bullion or coin.
