Is this french [επιλυμένο]

Hi hoping someone can identify this coin which appears to have been damaged by the plough I recovered it today when metal detecting .At first I thought possibly Louis 16th but the lettering is difficult for me to decipher .The coin appears to be debased silver .

 A picture of the other side also please. Also diameter. 

 Also the BORUSS lettering is on coins from German States. 

 Example: N#315417 

Obverse: Laureate head right

Lettering: FRIDERICUS BORUSSORUM REX 

 That is one example - other states have similar. I added some lettering … 

Hello! ''Borussorum'' means Prussia in latin. Friedrich The Great was,mainly,king of Prussia in the 18-th. century.

The coin is 26mm in diameter sorry the other side is very worn as you can see from the photo

 The denomination 1/6 Thaler was around that size, so may be this coin > 

N#174074 

Issuer: County of Kleve (German states) 
King: Frederick II the Great (1740-1786) 

Fantastic information thank you very much guys for that it is very much appreciated 

 A quick animation I made - the portrait and lettering look rather similar > 

Fantastic work thank you , definitely looks like that is it 😁
