Mitch,
Most of my figures are unpainted plastic, tssd, conte, etc of which I've painted up to reasonable average standards. I also have quite a few k&c and figarti 'premium' figures, and FOV figures.
but, if you take the unpainted tssd german longcoat figures for example, tssd also released factory painted versions 'soldiers of the world' of the same. Ok were painted up but were not brilliant.
From memory I think the unpainted set around £13 and the painted around £23. Not quite double but near.
I think my hand painted are superior to that of factory released tssd and would at very least be valued the same as.
With this reasoning I will suggest painted are valued at minimum, double that of unpainted, as valuation benchmark.
and very high quality painted, valued up to even treble that of unpainted.
Applying this logic to all scenics/accessories also.
What do you think??? is logical?
Thanks, Nigel
