The key difficulty with bidding data from these auctions is that bids only partially reveal information on the underlying valuations, bids shade the underlying valuations.
The valuation of the farms, farm-houses, and park, including 350 acres of land, was 36,000/; the mansion, 19,000/; and the furniture, 6,000/; making together 60,000/.
Conversely, widespread optimism can result in unjustifiably high valuations that will eventually lead to drops, when those high expectations don't pan out.
