old copper, nearly christian? , greek? [opgelost]

got this old coin im having trouble working out

i am fairly sure i can read

FA
or
ϜΔ
Diagamma Alpha

the way the A looks like an Alpha makes me feel the F is not a F but maybe this
https://en.wikipedia.org/wiki/Digamma
its used in greek, coptic,bactrian and albanian

https://en.wikipedia.org/wiki/Archaic_Greek_alphabets

I was told it could be from Aksum but i am unsure

my instincts tell me it is some early christian state around greece or the Levant , would love to hear what you think , or ever better an identification

I think it's more likely to be a small nummus from the late roman empire. The remaining letters are part of the usual ending "P F AVG".
