Take some good quality photos of each item, and a photo of them all in one picture. Then create a listing that describes each item in detail, so buyers know what they are getting. Be sure to list any faults, including any scratches or scuffs that might be present. Photograph any serial numbers and keep them. Don't add those to the listing. 

If you plan on having postage available, rather than just pick up, enquire to Aust Post, or courier companies about the cost of delivery before listing.
