Why does my brand-new fine gold coin (9999) have a conductivity value that's too high?

For some new fine gold bullion coins (e.g., 2021 Kangaroo, 2021 Lunar Series III), the measured values are at the upper end of the spectrum (usually 46 to 48.5 MS/m). As a result, the conductivity of some coins is displayed as too high on the GoldScreenSensor, even though they are genuine. This is likely due to a new type of ultra-thin coating on the coins, which is intended to protect them from damage. Therefore, as long as the dimensions and weight are correct, there is no cause for concern.
