Antiques can generally be appraised in one of two ways: in person or online. Sellers can use directories from organizations like the American Society of Appraisers or the Appraisers Association of America to find someone near them willing to do an appraisal. They can also upload photos for online use.
Having items appraised usually costs a small fee, which can be discounted or eliminated if the seller agrees to find a buyer for the item through the appraiser. It is important to find an appraiser who specializes in the type of item being appraised. The narrower the area of specialization, the more likely the seller is to get an accurate assessment of the item's value.
