Investigators from the Nelson-Atkins Museum of Art undertook this project to determine if worn-off or illegible hallmarks on silver and gold works of art could be imaged using scanning acoustic imaging techniques. Hallmarks and engravings from a total of 26 silver, two gold and one copper alloy (bronze) objects were imaged during the two-year course of the project.
