It shows some light, very old scratches on the Obverse consistent with commercial use (to the right of Liberty's elbow, not readily visible in our images), which are accounted for in the assigned PCGS grade. The point can be made that this is slightly undergraded from the technical surface preservation standpoint, compared to several other PCGS AU-50 coins I compared it to in the historical record, many of which were not even close to original. That should make my asking price reasonable for someone.
