Zambian independence

Surely there's something amiss with this coin:

The year given is 1974, yet the coin itself reads 1989. I think the picture(s) is/are wrong, because they are the same as this coin: https://en.numista.com/catalogue/pieces4443.html.

  You are correct - I have removed the images. Should be like on this page ...

   There are no members with the coin for exchange (probably as it is a Proof coin) but three have it in their collection, so maybe one of them could add the correct images. Thanks
