I noticed there are different variants of this coin

The form of the country name is different with different vocal signs.
Is this a known difference? Should there be two lines for them?

By the way, most coin sheets have the name written as
 بجمهورية مصر العربي
there are typoes; it should be
جمهورية مصر العربية
