Isn't that always the case? My friend was talking about a rare Magic The Gathering card being worth a silly amount of money... Except the card had only been sold once or twice at that price.
Unless you have enough comparable items (e.g. paintings by the Dutch masters) it's really difficult to determine the value of something that's rarely sold.
