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.

This research was made possible through Grant MT-2210-0-NC-21 from the National Center for Preservation Technology and Training (NCPTT).

One Response to Non-Destructive Imaging of Worn-Off Hallmarks and Engravings from Metal Objects of Art Using Acoustic Microscopy (2004-06)

    I am trying to find information regarding the punch stamping of a head and shoulders of what looks like a king with a crown or priest with a pontif within an oval. The piece is a cup with a handle, made of what appears to be silver with a copper or brass burnish on it. Handle is applied with a riveting/ saudering method. There on numbers on the bottom “27232” but I can’t remember if they are block style numbers. I can’t make out the words above the number.
    I only saw the piece once. Can you help me, please.

    I have pieces of my own that are silver/copper swirl from the Arab Egypt Republic, but the metal of my friend’s cup is not like mine. Is heavier and the handle is very crudely made.
