Larger images might help with just the date area. But here is what to look for on the small & large date 1970-S Cents.

1. The line on the Center of the 9 in the date.
2. The crease on the inside of the 7 intersection.
3. The tail of the 7 lower than the 0 in the date.
4. The bottom tail of the 9. Whether pointed or blunt.
The second image I would like to see closer. From what I can see it maybe a small date as well. A better image would help a lot. It could be from the dame die as # 1 as the mint mark locations look very close. I agree the # 3 is a large date.
