gold coins, page-4

I am not sure about this one, but during a certain period of the gold standard gold was circulating in the form of gold coins and not in the form of bank notes representing gold deposited at the central bank. So a sovereign would be, I imagine, a gold coin from that period.

The difference between a Krugerrand and a less known coin from the Perth Mint may be substantial depending on where you live.

If you live in Australia, as I suspect, then you would get less for your Kruger than if you were living in South Africa where the demand for Krugers is expected to be higher than here. That is, because in Australia a Kruger is harder (it takes longer) to be resold by the dealer, he or her in order to protected himself or herself against a fall in the price of gold is forced to pay relatively less for a Kruger than for a Perth minted coin.
