Step1
Watch "Antiques Roadshow" or "Cash in the Attic" to learn about antiques and which belongings may have value.
Step2
Get an independent appraisal first. This is a hands-on look at your item by an expert in that area. The expert can give his or her opinion of the item's worth and put it in writing.
Step3
Contact Sotheby's in New York with general inquiries about your piece to sell. The phone number is (212) 606-7010. Visit Sothebys website to be connected to a specialist who relates to your property to sell.
Step4
Arrange for a consultation of your piece in person. You can bring the item to one of Sotheby's galleries, where a specialist can give you an estimate of the value and possible sales price.
Step5
Have your piece evaluated by mail using photos of your item if you are unable to get to Sotheby's. Go to the Sotheby's website at sothebys.com and get an estimate request form to mail in.
Step6
Decide with your Sotheby's representative whether the item has the potential to sell at auction.
Step7
Look over the contract carefully and make sure you understand it before you sign it. Have the representative explain the reserve price (the lowest price) as well as their commission, which is a deduction from the final hammer price. Weigh the costs along with your item's potential to fetch a good price.
