Mexico 1980 date variations [gelöst]

The Mexico 1 peso 1980 KM460 has photos of the open 8 and closed It goes on to list closed 8 open 9, closed 8 wide date (no photo), and open I have several coin all with closed 8 closed 9. What are they?

I have just made macro images of the "9" as well, here the result



I think your question solved, if you say both closed and closed 9 and substitute the wide date with a closed 9
