Incorrect Year Printed?? [solved]

I was looking up a coin from my collection on numista, and was having trouble finding it. Well, eventually I found it, but it says it wasn't being printed in the year that is on the coin. The coin in question is this: https://en.numista.com/catalogue/pieces1030.html

My coin, however, is dated 1978. Do you think this is a misprint?? I am confused, and just want to have the correct information written down in my collection. Here is an image of my coin, front and back:

Also, I just noticed it's bronze looking in the picture. In person it is the silver color.

You have this type.

ah! thank you so much! I thought it was unlikely to be a misprint, but i couldn't find the right coin for the life of me! Thanks!
