I was pleased to find that an overnight soak in distilled water removed all of the grime from the reverse.
 
Obv. Unknown Emperor bust right ?VΤ ΚΑΙ - ? CCE within circle of dots.
Rev. assume Demeter bust right crescent above LΔE -ATOY within circle of dots.
9.6gr, 24.8-25.3mm & axis 12hr

Sorry, just can’t identify the Emperor.  Any pointers? 

Thanks

Perhaps I should have shown the rev. as Selene?

A little underweight buy somewhat worn!

Again, I am a suspicious person, but this looks like a cast to me.

Thanks djmacdo,
I'll send on some edge images.  I see another https://www.forumancientcoins.com/fakes/displayimage.php?album=search&cat=0&pid=19146#top_display_media
It belongs to a friend who think bought "sometime in the 60s" from a rummage box at fair.  The dirt did come off very easily - so yes now doubt it's authentic.

I don't have anything to contribute about authenticity (I wouldn't rule out genuine), but it would appear to be one of these:

Among the interesting types at Alexandria under Hadrian (and a few others) that spelled out the date (in this case, regnal year 11) as "L ΕΝΔΕΚΑΤΟΥ." (Reverse is Selene, as you suggested: "draped bust of Selene, with crescent, r.")

BTW, Here's a corrected URL (you can't copy from the address bar, you have to get the URL from the bottom of the entry for a Fake Report or Gallery Image). I think you meant this one (but it doesn't look like that's the same fake):

Thanks for the information.
I have added almost all of the edge.

Pretty suspicious edge.  The fifth photo down seems to show the remnant of a casting spur.
