Why does my brand new fine gold coin (9999) have too high a conductivity?

For some new fine gold investment coins (e.g. Kangaroo 2021, Lunnar Series III 2021) the measurements are at the upper end of the spectrum (mostly 46 to 48.5 MS/m). Thus, some coins show too high values, even though they are real. This is probably due to a new type of coating on the coins, which is supposed to protect them from damage. Therefore, if the dimensions and weight are correct, there is no need to worry.
