Victoria 6 Pence 1851 MS67 PCGS, Royal mint, KM730, S-3914. The second finest known specimen- this is the only MS67 example seen by either NGC or PCGS, with just one example graded higher (a PCGS MS68). Though by no means a rare coin, it is certainly a stunner with amazing old cabinet toning and completely original surfaces. This is essentially as good as they get!
