Tiny Ankh - Egyptian Silver Hallmark

I am happy to say that my silver sniping skills are becoming more keen. When I have a chance I will take another picture of this tiny ankh to show how small it is. I found it at the bottom of a box marked .99 stuff. Waaaay to tiny to see at the time is what I think to be an Egyptian silver hallmark. I am very excited, could anyone verify this is the mark for silver in Egypt.

The figure is of the Ankh, the Egyptian key of life, the key to the nile. Read more here: http://en.wikipedia.org/wiki/Ankh
