Can anybody assist by advising whether my observations on my 1964 cent are not unusual? That is other 1964 cents have the same issues. If not, then are these issues variations or errors?
On the 1964 Obverse:
The 'W' in WE is flush up against the rim while the other letters are not.
In the word 'LIBERTY', there a four sizes of the fonts i.e., 'LI' is small, 'BET' is slightly bigger, the top of 'R' is slightly higher than the others, and the top of 'Y' is slightly shorter. Pics below

On the reverse, there is a fat 'E' with 'E.PLURIBUS.UNUM'
Pics are below:

Th outline of the width of the 'E' is more clearer phyiscally than pic.
