Appraisers must instead estimate how much of a premium someone may be willing to pay, because of who owned the items. That is not an easy task.
The premium people will pay is different depending on the items and often depends on how closely associated the celebrity was to the item and how much it meant personally to the celebrity.
This makes things difficult for celebrity estate administrators, who must determine what personal items are worth for estate tax purposes.
It is quite common to have the situation of not being able to determine value, until the item is actually auctioned off.
