1970 50 Cents Slanted '7' Variety Curiousity

I'm calling coin 1 a slanted variety, but what has got me stumped is the other numbers.

I have two 1970 50c coins in the photos for comparison, coin 2 is not a slanted variety.

Ive done them double exposure so the two images are layered on top of each other, with the top image made transparent (faded) so both are visible at once.

In one photo I matched the 1's, the next I matched the 9's then the 7's, finally the 0's.

And they don't match at all, suprisingly the 0's made the dates clash the most, I did slant the top photo slightly I match the 7's and it meshed them the best.

I got two images from a website comparing the difference between the variety and non variety and did the same double exposure to them to see if it's just how if that just how it goes with dates, but they matched pretty good, just the 7 was slanted as expected.

So my two coins I was comparing to learn with, they say slanted 7? More like the entire date is mismatched.

1945 penny for your thoughts.
