Vintage 1983 Kenner Sand Scene Millennium Falcon MISB UKG Graded 80%

[jabbawalker]

Hi, I've recently had my 1983 Kenner 'Sand Scene' Millennium Falcon graded at 80% and I'm looking for a realistic valuation. There are 2 examples of this sandstorm scene version graded at 80% in the UK including this one. Any help would be hugely appreciated.
