What Was The Highest Auction Bid Per Sq. M. For Land?

I was watching today's auction rather closely, as there was a rare Grignano parcel in Nova Albion that went for L$255,010. It is a 1216 sq. m. parcel which works out to L$209.71 per sq. m. Does anyone know what the most paid per sq. m. in the Mainland Land Auctions has been? Or has anyone ever seen one that was higher?

I stopped bidding on this one at L$38,000! The old Brownstone Building Association just didn't have enough in the coffers to swing it.
