Gramma, have you read the FAQ on selling?
23) What is a "Featured Auction" listing? Featured Auctions are shown at the top of your allocated category and subcategory pages, in their own section above all the free and gallery auctions. They include a thumbnail in the search result and category listing pages. If you opt for "on first bid" or "run until sold" the auction will remain as a featured for 60 days before becoming a normal listing.
