I was looking at some recent Primadonna Tokens 1976 tokens and I notice some variations in the tokens.

The one on the far right has lines in her skirt compared to the other ones. Also the Primadonna is much flatter in design.

The one on the left seems to have larger skirt and the flume on her head is wider.

I find this strange since this was a give away and I would thought that it would had only lasted a few months (and why would they had needed 3 different runs on these tokens)?
