Egypt showcased more than 100 coffins dating back 25,000 years, the latest and largest find this year in the vast burial ground of the Saqqara Necropolis.
The 6th Dynasty coffins - sealed, finely painted and well-preserved - were of a higher quality than previous finds there, said the secretary-general of the supreme council of antiquities, Mostafa Waziri, suggesting they belonged to higher ranking families.
Fifty-nine coffins were unearthed in August at the same UNESCO world heritage site. More treasures are expected to be found there, said Waziri.
The newly-discovered coffins, plus associated mummies and artefacts, will go on display at the Grand Egyptian Museum, which is expected to open next year.
