Sa 1967 Pregnant Springbok 1 Rand Query

All,

My wife is admin of a facebook page for people who lived in South West Africa which is now Namibia.

A lady down there mentioned that she has a 1967 1 Rand coin which she put aside from circulation and wanted to know its value, so I get an instant message.

So I do a quick lookup and discover that has 0.3858 silver in it, so a quick calculation says the melt value should be around 103 SA Rand or 103 Namibian dollars.

Another person asked if it was the pregnant springbok version. I never heard of this.

Pictures have been asked for, but can anyone shed any light on the different versions of this coin. I will post pictures if they become available.

For example, what would make it a pregnant one? Does the variety exist on both the English and Afrikaans legend versions of the coin?

As always, thanks for the help.
Ken
