Watch List notes:

George III Pattern "Royal Cypher" Sixpence 1791, ESC-1647, plain edge, rare, PR55 NGC, slight obvious rub on Britannia, reflective surfaces, handsomely toned in shades of dark bluish gray. England produced very few patterns for the silver coinages during this time period, and here is one of the more interesting experiments in design.
