I found the info below on the internet, and I am thinking my top photo is a small date as all the numbers are level and "LIBERTY" is not as sharp, however that could be from wear.
PLEASE POST YOUR OPINION (if you have time).
Thanks !!!

Small Date Variety:
The Small Date variety is also known as the "High 7" variety. Even though "Small Date" is the more generally accepted term, it is easier to distinguish the two varieties by focusing on the location of the 7 than the size of the date itself. On the Small Date variety, the top of the 7 is even with the top of the 9 and 0 adjacent to it in the date. A second diagnostic for the Small Date variety is a weak LIBERTY which actually appears "mushy".


Large Date Variety:
On the Large Date variety, the numeral 7 in the date is noticeably lower than the adjacent 9 and 0 in the date. On the large date cents, the word LIBERTY is much stronger than on the Small date variety.


Like the general circulation strikes, the 1970 proof sets also can be found with large and small date cents. Again, the small date variety is the more valuable of the two.
