As Digital has already said. The last thing you want to sell is the most popular item. You would be buried under thousands of listings by high volume sellers and catagory spammers to the point that no-one would ever see your listing.
The best things to sell are the rarer items that no-one else has listed. The more odd ball it is the better, and some-one will be looking for it somewhere in the world. This often ( but not always ) means antiques and collectables as many of these are very rare or one-offs and collectors are willing to chase the rarer items hard as they may never see another one the same. An example would be hand painted pottery by early Australian potters / artists. Every one is different as they where hand painted and renowned artists works are very collectable. Another example would be early Australian carnival glass with rare animal designs and unusual colours. I have purchased rare items from antique shops and listed them on ebay and made good profit margins. I,ve also purchased items on ebay and sold them through fine art auctions and also had some very good results. It doesnt just happen. You need to study and develop a good knowlege of your chosen field. Do lots of research. Buy copies of auction records spanning many years. Watch items available on ebay. Do advanced searches on ebay for items sold in the last few months. All of this gives insights into what is popular and appreciating in value and what is going down in price.
If this seems all to hard, you can find a generic item that is not readily available in Australia. My twelve year old daughter had a thriving ebay business going for awhile selling stickers. It started when she wanted a specific quality brand, but could not find them in retail stores. It seemed no-one in Australia sold them on ebay as they where all coming from overseas. She found the original supplier on ebay ( by herself ) and purchased several bulk packs of 50 stickers with her pocket money that she had saved. They cost 55 cents each delivered and she sold them singularly for $1.65 each. Parents would buy a dozen at a time for kids parties etc. and she was making a small fortune for a kid.
It can take a bit of trial and error finding the right product, but with a bit of work and research you may find something suitable. There are still opportunities on ebay and products that are not being readily supplied.
Hope this all helps anyone who is looking to start out.
