Is there a site with pictures of these dates on actual coins?
We can supply the pictures.

Here's a pic I made illustrating the difference between the two letters Angielczyk names, which can also be seen on Jedi's link, as they appear on actual coins (a 1977 5 agorot and 1974 10 agorot):

The top stroke is longer on the daled, and it's horizontal. Most noticeably, it's asymmetrically balanced - the left "arm" is longer than the right one. On the zayin the top strike is tilted slightly (though this will be impossible to see except at high mag) but it's short and symmetrical.
For me, the numbers 5 and 8 can be even more challenging to discern - the only difference shown in both Krause and the illustration in Jedi's link is a small gap between two of the strokes, and on a worn coin it can be hard to say whether the gap is there or not. Here's an illustration of these two numerals as they appear on circulated aluminium coins (a 1 agorah 1975 and 10 agorot 1978):

I've found a better means of discerning them, particularly for these aluminium coins from the 1970s, is the location of the tiny "serif" where those two strokes meet - for heh (5), it's at the side, for cheth (8), it's at the top.
At least, I assume my interpretation is correct.
