The 'halo effect' is the result of wear on high spots caused by deformation of the metal in the stamping procedure. The numbers on the inside curve of the barrel flange are in a location protected from most wear, while the numbers on the shaft of the barrel are more likely to contact objects in use, particularly the acidic leather of the holster. Refinishing usually removes the high spots if buffing or sanding is employed, so that's why the 'halo effect' can be a good indication of original finish.
