I was reading a thread that discussed die polish lines, and I realized that I recently saw something that resembled this on one of my quarters. This quarter was recently pulled from a mint set, and there are a plethora of tiny excuse lines on the fields, and a quite a few on the devices as well though not as intense as the fields(see washington's neck). It was brought up that die polish are rarely found on the devices, so I was curious as to whether or not I'm looking at die polish lines? Here's a photo.
Although it's rarely found on devices, it still is at times. From the way your coin looks, it's die polish lines.
IMO they ARE die polish lines. Although it's a bit hard to tell from your image, the lines on the neck seem to occur only in the deepest area (hence the highest part of the die). If they don't occur at the base of the bust or on Washington's hair then I'm 90% sure they're from die polishing.
I see some behind the head that I think are die polish but I would tend to concur with Just Coins on this one. Most of what I am seeing look to be planchet striations. Die polish tend to run in many directions, planchet striations all in the same direction. All the lines on this seem to be roughly parallel and running from 12:00 to 6:00. There is a patch of lines behind the head that seems to be running as a 30 degree angle off the vertical. The die HAS been severely polished though, as can be told by the separation of the hair "ponytail" from the back of the neck.
true, there is also a very small patch on the cheek that is not present in the photo. I don't see them anywhere else on the obverse devices, nor on the coin's reverse.
