Roman coin identification and value required

 What is the diameter? 

Pictures roughly cropped. 

Hadrianus?

Yes, what's value of it

Maybe 15-20€ in this condition..

What are the weight and diameter? Is it silver or bronze? The patina leads me to belive it's one of those and-cast fakes from Morrocco. 

Like so:

Good day colleagues- and without stress.

     I've been dealing with this recently as well, and therefore I know that determining the metal is rather difficult. The coin should strike a special mixture ,, https://hmn.wiki/cs/Orichalcum,,

I had it as part of a large pile of coins stuck together with clay for a really long time, after washing in an ultrasonic washing machine in a special bath with demineralized water and adding substances, the result was somewhat different than the rest of the bronze coins. 

This leads me to believe that this alloy is a mixture with the addition of five to ten percent gold to the alloy ( (the coin showed a strange shimmer)

here, after taking it out of the bath, it is noticeable in the middle

To your coin - I also don't like the patina, which seemed to evoke a "desert patina"  In reality, coins that survive for this long are not uniform in patina across the board (or only an extremely small amount), however, an expert opinion will always recognize this.

I have to add: I meant the little scales that create the shine:
