Overall details of Very Good to Fine, significant strike weakness in an arc around the rim area from the 'D' of UNITED around through AMERICA and the tail feathers on the Eagle.  Some other signs of light weakness here and there.  Commonly regarded as 'struck through grease', usually left on the die from storage prior to being placed into service, however it could as easily have been water or something similar.  Otherwise no problems to note, given the actual wear.  An interesting coin, perhaps worthy of study.
