What does those letters on Austro Hungarian Empire coins mean?

https://www.ebay.com/itm/225113328554 ……

New here…searched for the meaning of letters on 2 austro hungarian coins I have to no avail, any one can help me with this?

 The two letters are not for a mint nor a person - it is two people; 

the “S” is for Tobias Schöbl and the “F” is for Joseph Faby. 

So S F = Schöbl / Faby joint work. 

 They made the original 1780 coin, of which yours is a restrike. 

'Below the bust you can find the inscription “S.F.”, this translates to the two names of 

the Günzburg mint officials in 1780,  responsible for the mintage of the original coin'.
