【 摘 要 】

This paper analyzes from the metallographic point of view the icon oklad (St. Great Martyr George), on which silver Russian hallmarks [1] are stamped in: The maker's mark-"PG" (PG), the assayer's mark-"IsA/1858" (IsA/1858), the silver standard mark "84" (.875) and the town mark. As a result of the optical microscopy and SEM-EDX investigations, it was concluded that the icon oklad was not made of silver alloy, according to silver title 84, but was made of silver plated copper. The presence of Russian silver hallmarks clearly indicates the intention to mislead. So it's a counterfeit. The hallmarks could be replicated (copied/falsified) after original silverware or by the old hallmarks that have been published in various catalogs [2]. Unfortunately, in Eastern Europe there is a large production of modern pieces with forged Russian hallmarks masked in old artifacts [3].
