These sqiggly lines IMO can only be explained due to pressure ridges developing and traveling along the Die Polish lines and due to the extreme pressure at which the coins is struck, the grease or oil also exerted pressure outwards on those created pressure ridhge lines.</p><p><br /></p><p>I edited and cropped the pictures of the coin and have attached them to this post.
