When you decide to sell a personal property item, you want to now the best market for your item and the most probable selling price. A good appraiser will determine the best market for your items. If you ask someone to value your items and they don't determine the best market, you can lose alot of money. For example, the "Best" market for original paintings from several top Canadian Artists is not even in Canada!
Market Value is the most probable price which a property should bring in a competitive and open market under all conditions requisite to a fair sale, the buyer and seller each acting prudently and knowledgeably, and assuming the price is not affected by undue stimulus. Implicit in this definition are the consummation of a sale as of a specified date and the passing of title from seller to buyer.
A professional appraiser determines the "best market" for your personal property item. In many cases, this can be in another city or country!
