Fingers are valued at 80 pence each, whilst a thumb has a value of 180 pence which corresponds to its use in ‘gripping agricultural equipment or arms’. The Iorwerth and Cyfnerth 5 recensions value a finger nail at 30 pence, whilst the top of the finger to the first knuckle is valued (in the same texts) at 26 2/3 of a penny. The price of a fingernail as it is valued in Iorwerth and Cyfnerth is 0.8% of
the "galanas", and intriguingly the thumbnail in the Wessex tariff also stands at 0.8% of the "wergild" value for the man.[7] Harris argues that these similar percentages reflect the co-existence of two legal systems in Wales; the Welsh and the English.
