So I have been wondering....how many times are coins supposed to be struck during the minting process? Once or twice? I have read that they are struck twice, but not sure. If struck twice then I have a question in regard to doubled dies. Doubled die variteties are made when the coin moves a little bit and the coin is struck again. But why does it only occur on the obverse or reverse or just in certain areas of the coin...rather than occuring on each face?
Normally coins for circulation are struck by the dies only once. Proof or special surface coins are generally struck 2 or more times. No, the doubled dies (before single squeeze die production), occurred when the working die was pressed ( squeezed) once by the working hubbing die, and then after removing the working die from the press and heating to soften it , it was pressed again with the working hub. If the working die/working hub did not line up exactly, a second overlapping image ( usually as strong ( height) an image as the first ) was produced. Thus the working die had a doubled inverse image and when it struck the blank , it produced a doubled die coin. Since the obverse die and the reverse die were produced separately, one or the other could be doubled irrespective of the other side. Now if the working die became loosened in its holder, it could move during the time of pressing a coin, this is Machine Doubling, and not a doubled die. Sometimes a coin is not ejected perfectly, it might be struck a second time, with the same dies and the result can have many different appearances, reasons, and names. Jim

Well it is 83 degrees right now. Yes, I am farther west and south than Las Vegas, and I knew that COINTALK is based in the east, so I honored it's time zone. Besides, I suspected I would forget at 12 midnight.
