The authors publish a semi-libral lead weight with three inscriptions designating the cost of the goods. The weight is dated to the late 2nd century AD. The inscription on lead gives the number of 192 ounces corresponding to the price for some amount of goods according to the Roman system. The inscriptions denote the cost in different denominations of copper coins current in the Bosporan Kingdom before and after Sauromates’ II monetary reform. The coins issued in the 1st c. AD were used in the kingdom as well as those issued in the 1st half of the 2nd century. That was the reason why on one side of the weight a trader marked the sum of money for the goods weighing 195 ounces (5.25 kg). This weight was given in different coins according to the system adopted in the Bosporan state before and after the reform of Sauromates II.
