  • WELCOME TO THE
    HALLMARK RESEARCH INSTITUTE (HRI)

    It is the goal of HRI to gather, disseminate and bridge the gap of hallmark images as seen by the observer to information the hallmark represents that is often lost to translation. The Institute's initial historical timeline concentrates primarily on the mid 19th century to current date.  In addition, HRI strives to clearly explain the hallmarking systems of countries across the globe and where possible define this information within the appropriate historical context.
    HRI means of delivery is presently through lectures. Currently,
    HRI is working on projects developing printed material and
    a searchable database on hallmarks.
