If you have never sold on an item at eBay, go to eBay's New User Tutorial and review the information there first. Honesty Makes Money People who are honest in their descriptions and responsible in their selling practices have the potential of making the most money, which means doing everything you can to make a bidder happy. This includes being prompt and answering questions. It also includes giving every little detail in a description, even if a flaw seems unimportant to you. Sellers who are honest and responsible reap many rewards here, including profits as well as friendships.
Many items are cross-collectible, that is, they appeal to a number of collectors and categories.
To List Go to eBay's Search Page and do a search in the Completed Search window, located at the bottom of the search page. Now search the results for a collectible identical or similar to yours. Retrieve the completed auction windows of the most successful sales. Note the categories used by the sellers. Note which category returned the best bids the most often.
