Thanks. On this obverse and reverse (which I don't often see this) there is what is called Ridge Ring. On the zinc cents we see this more as the die ages. DDD is often noticed on the fields in the direction towards the rim. After a die polishing, the breakdown of the die will show (on the obverse of your coin) the area that raises on the coin, (that flattens on the die) the a middle areas of the devices being thinned. (In God) On the next polishing, the devices will be thinned even more.
Kind of like your tires on your car. You can have part of the tread wearing down and eventually they have to be replaced. But on a die they try to rescue the die by polishing down the die. Thus eventually weakens the design more and more as more polishing happens to the die.
Same on the reverse but it is not as sever so far. But the devices are affected. That is what your are seeing on your coin. The weakening on the UNI on United. Same on the 'O' on ONE. The other boxes are die polishing scratches. So your next question will be: "Why are some areas showing die scratches and other areas not showing die scratches?" Die scratches wear differently on a die. In the open fields, they flatten and go away face. But die scratches near a device, will last a lot longer. Ones in side a contained area like in the bays and in side of the devices/bays will last the longest. Thus on your coin, it is showing this. Thus some are more protected than others. But aside from the things already mentioned, on the head on the obverse, we see die scratches there and the ones on the reverse are telling me it was polished because of a die clash event:
On a die clash the deeper devices will be showing more on the clash. The outline of the bust and the Building are the most often seen on a clash. But that event has been polished off the die at this point. So the die scratches are telling me this is the reason the die was polished. It was not an issue with a Feeder Finger Damage issue. Those other event will be affecting dies differently, than a clash event. Hope this helps. If not, ask what is not clear.
