Oh - didn't see that.

If I'd decided to sell out of my collection instead of giving it away, I'd have had some parallel cases - any large enough collection is liable to include a small but significant proportion of one-off parts. I'm not sure a 2x4 black brick is likely enough to sell that it'd be worth listing alone, but I suppose someone with a sufficiently completist bent might go to the trouble.

I wonder if they bought some sets, and are selling based off known contents - since they're technically pre-sorted.
