Don't see many of these about. Well, any, actually. I've not seen one, anyway, which isn't necessarily the same thing
I'd say this is one of the rarer 45C cards. I've checked tracker and there are none on there, either.
However, rare does not always translate to megabucks, particularly with the less rated 45C and 65 back Palitoys. The lack of the Palitoy logo, indeed any logo, makes them less interesting in some eyes. Seeing as I like the cardback images I'd disagree (although the Jedi logo is poor vs the ESB logo on 45B cardbacks).
If he were mine I'd take him to auction. He ticks a number of focus boxes for a number of collectors, me included, so I will be grateful to know where you list it up for sale, if you are.
