was a square piece of gold coin, commonly valued at 30 pence; and mancufa was as much as a mark of silver, having its name from manu cufa, being coined with the hand: (Leg. Canut.) But the manca and mancufa were not always of that value; for sometimes the former was valued at six shillings, and the latter, as used by the English Saxons, was equal in value to our half crown. Manca sex solidis æstimatur, (Leg. H. i. c. 69.) Thorn in his chronicle, tells us, that mancufa est pondus duorum solidorum et sex denariorum; and with him agrees Du Cange, who says, that 20 mances make 50 shillings. Manca and mancufa are promiscuously used in the old books for the same money.
