Correct way of identifying faces of notes

Good Evening All,

One thing puzzles me when It comes to identifying face and back of banknotes.

In the UK the face of the note is the denomination with the Image of QEII or KCIII and the back is Churchill

Now the Serial numbers are on the front of the notes, should this be a standard procedure or is this down to corresponding Countries as in my collection I would have the English side as the face of note, for example my Egyptian notes are showing the Arabic side instead of the English side

What is the correct way to tell face from back?

Thanks 

Standard rule is that the front (obverse) of a banknote is always printed with the national language of the country. On the reverse side you will find the note printed with a foreign language (English or French) and perhaps with a mixture of their own national language.

Obverse

Reverse

Same rules applying to your Egyptian notes. Arabic printed on the front and English printed on the back

As for serial numbers, there are no rules to this. Australia current banknotes are printed with the two signatures on the front and the serial numbers are on the back.

Thank you for your response Ahkai 👍

Also, the title of the issuing authority, ‘Bank of England’, ‘Federal Reserve Note’; ‘Banque de France’ etc, will generally be on the face of a banknote, as would be the signatures of officials.
