About the Appraisals

There are two basic types of appraisals.

Insurance appraisal is used to determine the retail replacement cost for insurance scheduling. The value that is given to your piece is the price upon which your premium is set. A detailed description is crucial in order to replace the piece if necessary with an item of equal quality and kind. Because of this, it is very important that the descriptions be extremely detailed and specific.
Fair Market Value appraisals can be used for a variety of purposes, including cash liquidation, collateral, divorce settlement, investment, estate probate, and charitable contributions.

In order to determine which type of appraisal is right for you, it is crucial to tell your appraiser what you intend to do with the piece, or the reason why you are looking to have it appraised.
