Watch List notes:

Sovereign 1850 with a 5 struck over the 8 of the date, a recently discovered type, NVF/Good Fine and extremely rare, the overstrike extremely bold and clear. This the same variety as the coin listed in the Bentley Collection (Lot 986), where it was stated 'the cataloguer has heard of only one other specimen extant' and that the Bentley collector waited 5 years to acquire his example. We note the Bentley example, described as 'Cleaned, Good Very Fine' realised £2520 in May 2013. In the light of this, there will be few opportunities to obtain this coin for any advanced Sovereign Collection, and it may be many years before another example is offered

Estimate: 1000-2000 GBP
