Yes, 1644-45 General Assembly's Act VII. It was a about law about the abandonment of property. The issue in the colony mid-century was the general poor construction of houses, the shortage of housing for new arrivals into the colony and an effort to solve that problem making it illegal to burn structures when abandoning property and paying in nails for structures in nails -- the little tiny grain of truth within the myth was colonial authorities paying off in nails. This was also a period where house construction evolved in the colony from a low nail consumption to high volume of nail consumption construction with wattle and daub infill going over to clapboard cladded houses. Also burnt houses are not going to render very many useable nails many twisted and mangled. Those nails used in the construction of doors and shutters also were clinched over.
As far as an actual price a historian at UC Davis settled on 4d for the price of a pound of nails in the first half of the 17th century. The principle cost being the material over that of labor.
It is worth considering the poor laws, poor relief and the ability to put children of poor families into workshops... like naileries. Then jump to the future and Adam Smith's comparison of blacksmiths and nailers.
Book 1 Chapter 1 of The Wealth of Nations --
"A common smith, who, though accustomed to handle the hammer, has never been used to make nails, if upon some particular occasion he is obliged to attempt it, will scarce, I am assured, be able to make above two or three hundred nails in a day, and those too very bad ones. A smith who has been accustomed to make nails, but whose sole or principal business has not been that of a nailer, can seldom with his utmost diligence make more than eight hundred or a thousand nails in a day. I have seen several boys under twenty years of age who had never exercised any other trade but that of making nails, and who, when they exerted themselves, could make, each of them, upwards of two thousand three hundred nails in a day. The making of a nail, however, is by no means one of the simplest operations. The same person blows the bellows, stirs or mends the fire as there is occasion, heats the iron, and forges every part of the nail: In forging the head too he is obliged to change his tools."
