Thank you. I was unaware that the coin weighed more than 1 troy oz.
The South African Krugerrand is 1.1 ounces, 1.0 ounces is gold and the other .1 ounce is copper. Pure gold is to soft to make into coins without an alloy. The copper gives the Kruggerrand it's distinctive 'red' hue. I bought many of these in the early 90's for $382.00 each.
I wish I had kept more of them than I did.
