Hard to say from that pic. die polish lines should be raised above the surface.......those could be whizzing lines if they are into the coin. use a 17 power lens and hold the coin at an angle in very good light.

It's almost impossible to tell the difference between die polish and hair lines from any picture. You need to hold the coin so that the light shines across the lines and look at it with a loupe. With die polish, the light will hit the near side of the raised line, casting a shadow away from the light. With hair lines, the light will jump across the trough of the scratch and shine onto the far bank of the scratch. It may be necessary to look at it from the opposite angle as well in order to be sure whether the line is raised above the surface of the field or sunken into the field.

This is something I still have a hard time with. If a coin had hairlines would they not also show up going through the lettering and raised parts of the coin as well? These look as if they run under the lettering and high points. I also want to get this right too

construct

A strong hairline, like a gouge, will sometimes be evident running across a device. However, sometimes a device will obscure the hairline so that it's difficult to see. Die polish will be confined to the fields. (One big exception--with Indian gold, all bets are off about how die polish behaves.)

I came across this old thread today and thought it should be noted that die polish has occurred on the devices for other series as well, especially die clashed Ike dollars where there are countless examples.
