Use a reserve-price auction for items with unknown value or limited appeal.
One of eBay’s greatest strengths is the lengths to which its policies go to protect its millions of users, both buyers and sellers. One of the best known of these policies is the reserve price, which subsequently gets overused.
A reserve price is a dollar amount the seller specifies, below which he or she is under no obligation to sell. For example, you might want to sell a car for at least $15,000.

If a reserve is set at $15,000, and no bids exceeding that amount have been placed by the end of the auction, then neither the seller nor the high bidder is under any obligation to complete the transaction.
