I don't really know much about loose figures as I've always been a MOC collector, however from having owned every figure at some point, I do know that the US and UK figures were quite different. The UK figures often had sloppier paintwork, different shades, and 'shinier' paint. Here's a good example:
As you can see, this Luke has bright yellow hair, really dark boots, the paint looks like it was applied by a 5 year old, and just looks less matte than the US Kenner figure does.
So my question is, how do you identify these 'Palitoy' figures when they're loose? Do they have a particular COO or something? If I wanted to try and collect these figures specifically as opposed to Kenner ones, how woould I do that without buying Palitoy MOCs and opening them!?
