Could anyone please give me a quick explanation of the manufacture of early milled silver? I have read some of the strawing process which suggests that some of the black flow lines in the early silver coins are the result of putting the hot planchets once die pressed onto to damp straw. Were the planchets hot when introduced to the press? there are some interesting old images of the milling process but I cannot find out the exact process, or just have not looked hard enough. I have read the books on the changes that Sir Isaac newton seemed to have some responsibility for when keeper of the mint but there is not a lot of detail. I am particularly interested in the later 17th C and early 18th C although as I see the same in GII coins up to mid 18th C. Some help please. THanks
