Early Byzantine Seal Bust Left or Manus Dei or Menorah 5th or 6th Century ?

[pogh_poor]

I just purchased a very early Byzantine or possibly late Roman seal.  It measures approximately 14.76 mm and weighs 4.72 g.  

On the obverse, I believe that there is a profile saint or other individual left.  The dealer suggested it may be Manus Dei but I don't thing so.  I have seen an early Byzantine seal with a menorah  which maybe a possibility.  The image is within a ring of leaves.

On the reverse, there are 6 characters which may read    
or   R      The inscription is within a ring of leaves.

It appears to be late 5th or early 6th Century to me.  Thoughts?

Here is an example of a seal with a menorah  Pogh_poor

I have never seen anything like this. Pretty sure it is not a Menorah, though. Could be a hand of God, but I know no parallels for this time period. Inscription maybe ABPAM-abbreviation mark? Abram(ios)

I didn't recognize the   at first.  

Could it be:
     
   

And solve Ἀβραάμ =  Abraam = Abraham?  

Also does my dating seem correct?

Yes, dating seems to be around that time.

I read on the last line:

A M'

So a heavily seriffed M with a 'comma' like abbreviation mark. Abram(ios) is the Greek form of Hebrew Abraham.

Yes I see it now too. I was over complicating it.   Pogh_poor
