Strange krugerrand

So, I have another coin bought from a reputable dealer in Linköping, 25 years ago. 
It's a rand from 1975, it's extremely small and I can't measure it but I assume it's 1/50 rand.
 

The problem is that its lacking the value, all rands should have a value written on it.

So, there is some options. 
1. It's fake and the dealer was tricked 
2. It's some kind of memorial coin
3. Mistake in production
4. “Tourist coin”, according to ChatGPT South Africa sold these to tourists 

I guess more options is available. I need some help to identify what this really is.
 

Compare the diameter/weight to this one I entered in the Exonumia catalog.  I can see it's not identical but may be another example of a miniature.  N#355431

Sadly it doesn't really match, I think that they started to produce new series after 1980.

Is it possible that the weight text can be missing on a real kruger rand?

No.

Maybe this one?  N#87656

Yes, it looks similar but mine is “mint”, looks totally fresh and new.
Is it worth anything?

Is it gold?

I'm 99.99% certain its gold and the seller had 40 years experience, his daughter's has taken over the shop now. 
 

Weight, diameter, thickness?
