So much going on with your coin, but I see nothing as a premium for your coin.
1. The mark around the head is part of a trench that appears on dies of that time. I wasn't there during those days, but it may have been something to enhance the edge of the bust.

On your coin the trench is wearing away and now the outline edge is making a mark around the head.
2. The rippling above LIBERTY is fading heavy die scratches. They flatten out with time leaving a ripple effect. This also seen through central devices on the reverse.
3.Heavy die wear is seen on all devices that face the rim. It tends to distort the devices from what they were when the die was fresh.
4. The letters on ONE on the reverse are showing
Machine Doubling. Note how one side of the devices are thinner.
5. Figure in circulation flattening and contact marks, it makes the coin look different from what it originally started out. Nothing good to report as far as a collectable.
