Electrician, thanks for the additional pics. This is a very minor and partial
Ridge Ring.. like I mentioned earlier, it occurs at the striking. The blame can be put on a deteriorating die, the flow of metal and the copper plating. It's pretty common. As far as a premium, I can't say as I've never seen one sold.
Or a quarter that was in a coin bag that was buried under other bags on the back of a truck that happened to precisely line it's self up exactly with the W on that penny just as the truck rode over a speed bump imprinting a reeded edge and mashing that W downwards as it is now... I think I got that right, Crazy?
Electrician, happy hunting! You have a sharp eye, keep it open.
