Mark and markings on silver cross pendant

This cross pendant is about 2 inches tall, and tests silver. The mark on the back side at the bottom is almost impossible to read. There is also a small mark on the bail. Can someone point me in the right direction as to what country this might be from.

Also, what is the meaning of all the letters on the front of the cross? I have googled various combinations of the letters and come up with nothing.

Thanks for any help!

 

It does. That's a Coptic cross I believe.

 

Thank you both. I am confused by the English letters.

 

It has the town mark of Alexandria, Egypt:


I am not too sure about the date letter, it could be 1978.

Coptic letters. Egyptian Coptic script has Greek script elements.

 

Thank you AJ!
