MANCA, was a square piece of gold coin, commonly valued at 30 pence; and manusa was as much
Mancancel as a mark of silver, having its name from manu-cusa, being coined with the hand. Leg. Canut. But the manca and mancusa were not alway 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 aestimetur. Leg. H. 1. c. 69. Thorn, in his chronicle, tells us, that mancusa est pondus duorum solidorum et sex denariorum; and with him agrees Du Cange, who says, that 20 manca make 50 shillings. Manca and mancusa are promiscuously used in the old books for the same money.
