Minifigure prices are real completed BrickLink sales. The parts figure is an estimate — the set’s own inventory at the catalogue average, not each piece priced individually. Treat it as a guide, and remember parting out is hours of work and many small sales.

eBay links are affiliate links — if you buy after clicking, we earn a small commission at no cost to you, and that is what pays for the site. BrickLink has no such programme, so those are plain links. Neither changes what we show or what we say about it.
How to read this. The value is the median of live sealed listings, after removing instructions, empty boxes, used sets, multi-set lots and implausible outliers. Real sale prices usually land below asking, so the buy-below figure is deliberately the conservative end of the range.
