If HA only put low-value junk in the weekly auctions, far fewer people would bother looking at them. High value lots like this make people check the auctions every week. On top of that, if you ignore the July result, this was actually a pretty strong result; a 9.6 A++ Collector's Edition sold in April for $31,200 all-in, so this seems in line with that. For all we know the consignor was perfectly happy to sell this lot now, while we know the market is strong, instead of waiting however many months for the next available Signature auction, by which point the market may have cooled off even more.
