Certified ANACS AU-50 in an old "mini slab".  Doubled Die Obverse, Fletcher-6, Spindel S1-1005 (NGC Variety Plus VP-004).  Fletcher shows this as URS-4 (less than 9 known), Howard's site shows 3, the highest EF-45.  Not a PCGS recognized variety, as they only cert a small number of Cherrypicker #'s; one single VF shown in the NGC census.  I am sure there are a few more lurking out there, however certainly not common as a variety, and not all that common in the grade as a basic 1876, despite some saving due to the date's connection to the U. S. Centennial.
