The first, discovered in the Karnak cachette by Georges Legrain,[4] is missing its head and feet and gives the king's nomen and prenomen as well as a dedication to the god Sobek, lord of smnw.

Another possible attestation of Merankhre Mentuhotep VI is given by a fragment of a wooden coffin, now in the British Museum under the catalog number BM EA 29997.

To decide between the two remaining kings, Ryholt notes that the other instance of the Book of the Dead is found on the coffin of queen Mentuhotep, wife of Djehuti, the second pharaoh of the 16th Dynasty who reigned c. 1645 BC.

This identification is far from certain however, and Aidan Dodson and Dyan Hilton have instead dated the coffin to the end of the 16th dynasty, thereby giving Herunefer as the son of Merankhre Mentuhotep VI and Sitmut as his wife.

Second, the first statuette of Merankhre Mentuhotep is dedicated to Sobek of smnw (Sumenu) and was therefore probably set up at el-Mahamid Qibli near Gebelein where both Dedumose II and Djedankhre Montemsaf are attested before being moved to the Karnak cachette at a later point in time, perhaps at the collapse of the dynasty.
