That’s what I mean with ‘collectible’ - the Lego market is an odd kettle of fish where items are priced beyond what we would normally expect to be toys, where models have their very own look and style - and can yet end up as presentation pieces on the desk of an architect or engineer. Or in the sandbox next to some battered Matchbox models.
Thing is, merchandise today turns up in every price segment of the market, there is nothing really exclusive any more, just varying degrees of walking as an add. The trick is to work all segments of the market, to offer something for everybody. That’s why comic figures and game characters come in ridiculously priced limited edition models these days. Articles whose worth is solely defined by what their customers want to shell out for them.
