Tables 7: Penny Nail
The term "penny", used with nails, was an English measurement originally meaning price per 100. It now means nail length and is abbreviated "d".
Under the original measurement, 6d nails cost 6 pence per 100. A 60d nail, being much heavier, cost 60 pence per 100.
With the new system, the different penny sizes refer to lengths of nail.
