1) I would change “Medium” to “Large” to match the current year line comments. Medium doesn't really make sense if there's only two sizes.
2) Remove the “Small over line / Medium below” comment. Exact placement of mint marks on these coins is somewhat random since they were hand stamped onto each die individually and thus the exact location varies on each die. Here's an example of 1934D coins where the Small D is below the Large D:

1971 should be 1971D
Still looking at the others km's.
Do you have those images without the line and in hi-res, since I think they are better than the ones I used!
1) 1979D - position of D/Thickness of rims - I think you should remove all references to the position of the mint mark D. As explained above, the position changes somewhat on every die as they were hand stamped individually and does not constitute a variety.
2) 1979P - position of P - same, don't use.
3) 1979P - position of P/Thickness of rims - same, remove references to position and thickness of rims is already shown in next slide so this graphic is not needed
4) 1979P - narrow and wide rims - pictures of obverse are switched. Narrow is in the center, wide is on the left.
5) 1979S - position of S/Thickness of rims - same, remove references to position

Change “boldly” to “boldly detailed” (2 places) and move the arrow on the left picture to point to the tail feathers
