You put your 10X glass to your eye, bring the coin up to the lens until it gets into sharp focus and you see this:
Raised lines on the surface only of a coin is usually die polishing lines. Yet I am a little confused at what you are leading to with your poll answers.
spirityoda, requested: "Let see the whole coin pic." You must be new around here. No, heck no, never! Because...you don't need to see the whole coin to answer my quiz.
Die polish. The striations are unidirectional, and not swirled, nor deviating into more than one direction. They are South to North on that picture.
Another one that I am at something of a loss. In a thread the other day, you used a term I had never heard before, micro-whizzing.... Could this perhaps be a micro-whizzed dollar?
Other. Die polish lines. Straight, uni-directional, visible right up to the edges of the devices on both sides of the devices and in the otherwise protected internal areas of the devices, such as the interior of O and U.
I go with a harshly cleaned, wire brushed, die. So, die “polishing”. Except they ought to have actually polished the die a bit after they wire brushed the gunk off of it.
What I mean is that if a coin is wire-brushed, the interior edge of the O will not allow the brush to get into that constricted area right up against the raised edge of the device. So the interior of the O is "protected". On the die, however, the device is incuse so the lines can go right up to the edge of the incused device.
Yes, I understand, and interpreted your post in that manner. I am not being clear: I am referring to the raised (top) highpoint portion of the "O".
I'll just add that a little die deterioration doubling is consistent with the need to polish the die. But this is definitely out of my area.
As has been stated in other threads, the existence of one type of lines does not preclude the existence of other types of lines on the same coin. To illustrate, it is possible to have both die polish lines and post-minting hairlines on the same coin. To @charley's point, the O has some post-minting damage contact marks. There are also some marks on the top of the O that are angled at about 20 degrees from vertical and the same angular displacement from what I have called die polish lines. There are also numerous, very short lines at that same angle in the fields to the upper right and right of the O which I interpret as some light circulation or hairline marks and thus not germane (IMHO) to what @Insider is getting at.
Thanks. I simply wanted everyone to have a level playing ground. And, not only the"O". Thank you for the illustration, but I think I just maybe be a little familiar. How do you know if it is or is not germane? It darn well would be germane to the Grader and the Grade. Maybe you didn't see the lines at first, but finally did. Maybe that is what the point of the exercise is/was. I don't care either way. The issue was calling attention to "lines" also on the devices.
