Antiques can be sold online in a wide variety of places, but the most popular site would be eBay. eBay allows you to sell antiques quickly and almost guarantees that the item will be sold.
The auction format would be recommended, but fixed prices can be set as well. Fixed prices may take more time to sell and prices may need to be negotiated with buyers. For example, if you are selling a piece of antique furniture with a reserve price of $200, then somebody would have to bid that amount for the item to sell. If no reserve price is set, then that same piece of furniture can sell for as low as a dollar. eBay does also charge a fee whether the item sells or not.
Another common place to sell antiques online would be Craigslist. Craigslist allows the seller to input their location and the item they are selling along with a description. They can also put their contact information so potential buyers may contact them. Craigslist is completely free with the only caveat being this is not a professional selling method. Buyers may want to meet at a location and do the exchange in an informal manner. Also, it may be more difficult to sell an item on Craigslist due to the buyer not trusting the authenticity.
Another place to sell antiques online is Ruby Lane. Ruby Lane is known for exceptional customer service and they attract large amounts of traffic. Traffic is the most important factor in selling items online, so the more sought after the item is, the more likely the item is to sell. Ruby Lane has thousands of items for sale and is just one of many online sites used by antique buyers & sellers. The antique business is a competitive market so multiple sites are available to sell an item online. The benefits of a site like Ruby Lane is that they take excellent photos, provide lengthy accurate descriptions, list any faults with an item, and categorization of items is correct, which all help in keeping the integrity of the site intact.
Etsy is another website that has a huge vintage market for selling antiques. Most people associate Etsy with handmade items, but Etsy has a requirement that for any listed vintage item it must be older than 1996. It is cheap to list an item and it stays there for four months. The current cost is only $.20, which is a lot cheaper than most other sites. Etsy is easy to use and just one of the many online sites available for selling antiques.
