23k auction

Previous 38 sale on MP is in-date, but given buyer is now selling for 35: https://gyazo.com/3af1582696935f78c16b732518b66059 and the two more recent lower sales, inclined to think that is high now.

Given 23 was an auction and also slightly below generic buyers (23.6k), excluding that.

25-26.
