Hi
after discussion with Apuking, he still think it's km 39 and not 38.
clearly the figure 6 is different and the letters H•F are below the eagle's left leg and not above like km 39.
does anyone have a German catalog to check it out?
thanks

Your coin is not KM#38 but KM#39. KM#38 has the mintmark CS while the KM#39 has the mintmark HFH. And for both coins their exist varieties (I guess like the place of that mintmark).
