Yeah, I know that - they're rarer than ones without the free gift.
Rarity alone doesn't dictate value, though - that's a function of the perceived value. Supply & demand, right? Fer'instance, a 2000AD prog 1 with "Martin" written on the cover in red biro by a newsagent in Birmingham (example chosen at random) is rare, but has no perceived value over and above that of a comic with "Fred" written on it.
So the supply is low, but there still has to be a demand for that to push the price up. And the demand has to be pretty strong for "with free gift" to put 200% on the value (prog 1, from a dealer, is ?50 - with the free gift it's ?150. Same happens in a free auction on, eg. eBay - with free gift is around ?100 more than without).
So that piece of plastic is worth more than the comic itself *even though it will not be played with*.
Which still leave the question of: Why? Why does the addition of a (by definition, useless) "free gift" add ?100 to the value of the comic? Why does that demand exist. Unless.
Nah. But...Unless...Is it just collecting for collecting's sake? Little to do with the comic, but just a round-robin of people who have agreed (informally, and without collusion) that "rare" equates to "valuable"?
Or is it a vicarious thrill thing - that this comic is *exactly* as it was when released? How about a signed copy, though? Signed by - oh - Pat Mills, say, but with no free gift. Would that be worth more or less, do you think, than an unsigned copy with the free gift?
It still comes down to the twin questions:
Just how much is that free gift worth? (On current evidence (eBay, dealers), twice the value of the comic it came with); and
Why is it worth *so* much?
