Victoria 6 Pence 1843 MS66 PCGS, Royal mint, KM733.1, S-3908. The surfaces are impressively silky with tone that strengthens at the edges. The single finest example in the PCGS census and more-than-likley a coin that is destined to remained unsurpassed in quality. For the variety collector, it's worth noting that the first three "I" in the obverse legend appear to have been punched with a "1", with the error being caught and corrected thereafter.
