OBVERSE AND REVERSE FONTS
Here the fonts are similar, though the letters are necessarily narrower on the reverse, showing Kenyatta, because there are more words.

On the 2005 version of the 50 cents, the obverse font is now distinctly
sans serif, while the reverse font is
serif.

On the Arap Moi coins, the font is of the same type on both sides.

These same differences apply to the bimetallic coins.

Most standard circulation coins, I believe, have similar fonts on the obverse and reverse.
How many do you know of that do not?
