Hong Kong, Victoria, dollar, 1866, diademed head l., rev. value and date within ornate border (KM.10), in plastic holder, graded by PCGS as Mint State 63
£12,500-15,000
The only thing preventing this and the 1867 dollar from grading much higher are the bagmarks on the obverse. This is freshly mint state, one of the finest we have seen.
