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