SOFIA, BULGARIA—Eighty-two silver coins, some bearing an image of the head of King Philip II of Macedon, were recovered by Bulgaria’s customs agency at Sofia International Airport. The coins were hidden in three routers in a package headed for the United States. “Each of the coins is a cultural artifact as per [Bulgaria’s] Cultural Heritage Act. In addition to their extremely high financial and collectors’ worth, the coins are also priceless from a scientific point of view because they are completely unknown for the historical science,” read a statement from the Customs Agency in Sofia, reported in Archaeology in Bulgaria. Customs officers are continuing to investigate the case. They have not released any information about where the coins may have been unearthed.
