BUDAPEST, HUNGARY—Seven of the 14 pieces of the Sevso Treasure have been purchased by Hungary from unidentified sellers for 15 million euros. The attempted auction of the silver hoard was halted in 1990 due to false documentation on the treasure’s provenance. The fourth-century Roman silver is thought to have been unearthed illegally in the 1970s near Lake Balaton in western Hungary. “Hungary’s family silver is coming home,” Prime Minister Vikto Orbán told the Budapest Business Journal.
