for a coin such as this one, in order to arrive at an approximate value, you need to have an accurate idea of its grade.
There are huge value differences between
Fine (F),
Very Fine (VF),
Extremely Fine (EF,) and
Uncirculated (Unc).
(British grading system) - necessary in this case because you intend to sell in in the U.K.
Grading is affected by wear, damage such as scratches and the degree of luster in higher grades.
With this coin I notice that there are flat areas of wear on the high pounds such as the leaves (obverse), and leg, helmet and chest of the dragon (reverse).
The amount of wear on this George 1111 gold sovereign would equate to a grade of Fine condition.
Tony Claytons Coin Values is my 'go to' site for current British coin values.
He lists this coin in Fine condition at 450 Pounds.
