Testing a new sampling method in Frankfurt

Prof. Sabine Klein from the Bergbaumuseum, Bochum is testing a new method of obtaining material from coins for analysis using quartz rods to take minute samples from their surface. It is hoped that in this way it will be possible to obtain samples from gold coins in the field outside a laboratory and without drilling them.
