Can I test all coins and bars with the GoldScreenBox?

You can basically test all bars and coins with the GoldScreenBox. However, there are cases that limit an accurate measurement.

For thicker objects (over 50/100 grams, depending on the dimensions), we recommend using the BarScreenSensor to protect against thickly rolled gold plating.

With old coins (before 1945), impurities sometimes occur. On 986 ducats, for example, only 986/1000 parts are gold, the rest is ideally copper. However, since the separation process was not yet sufficiently perfected at that time, these 14/1000 parts can also consist of other metals that falsify the conductance.

In addition, particularly thick blisters and capsules (>3 mm), such as NGC-packaging, cannot be penetrated by the GoldScreenBox.
