Make the image as sharp as possible. If you have photo studio software, shrink the size. The image should be large enough to show detail but small enough so it loads quickly, usually fist-size or smaller. Include additional photos of close-ups, signatures, manufacturer marks, and so on. For more information, see eBay's photo tutorial .
Collectors particularly appreciate a guarantee of satisfaction.
If you offer one, include the terms of sale in your description. When you quote terms, be informative and positive, not preachy or negative. There are escrow services available for a small fee if the buyer would like to see the item and accept it before payment is released. See the escrow section for more details. Just as key words are important in a title, they are equally important in your description.
