BUDAPEST, Hungary (AP) — Hungary's prime minister says the government has bought the remaining seven objects of a Roman-era silver treasure believed to have smuggled out of the country in the 1980s.

The 14 silver trays, bowls and jugs, plus the copper cauldron they were kept in, are known as the "Sevso treasures" from the 4th century, when western Hungary was part of the Roman Empire.

Prime Minister Viktor Orban said Wednesday that "the place for our invaluable national treasures, the family silver, is in Hungary."

Hungary purchased the first seven objects in 2014 for 15 million euros (then $20.7 million) and paid another 28 million euros ($31.9 million) for the current batch to undisclosed sellers.

The treasure is thought to have been found in the mid-1970s near Hungary's Lake Balaton.
