In this way, what does a penny nail mean?
The term "penny", used with nails, was an English measurement originally meaning price per 100. It now means nail length and is abbreviated "d" from the old Roman "penny" the denarius. Under the original measurement, 6d nails cost 6 pence per 100. A 60d nail, being much heavier, cost 60 pence per 100.
An 8d nail, for example, cost 8 pennies for 100. Today, the penny system refers specifically to nail length. A 2d nail is 1 inch long, for example, while a 16d nail is 3 1/2 inches long. Each higher number in the penny system represents a 1/4-inch length increase, up to a 12d nail (3 1/4 inches long).
