Abstract

The object is one of 46 ancient coins found at the archaeological site of the former Roman colony of Mursa ( today's city of Osijek ), in the province of Pannonia. This particular coin was picked up not only because of its state of preservation, but also because of the interesting life and political significance of the emperor Aurelian whose head it portrays. The coin is made of copper alloy. When excavated, it was covered in soil containing calcite. The presence of the metal core was established by boring the coin with a needle. The coin also showed the type of corrosion commonly referred to as "bronze cancer". Soil and calcite accretions were eliminated with a scalpel, synthetic brush, and a micro-motor grinder with a flexible shaft. The stabilization process began with dipping the coin in the 3 % solution of benzotriazole in acetone. The coat of Paraloid B72 in toluene was used as the protective finish.
