It isn’t easy but you can make quick cash on eBay. It took me around a year to figure out the best stuff to sell on eBay. The three most important things I learned about selling on eBay are to have patience (because it can take months for items to sell), make sure you post at least one really good picture of your merchandise and try to find a niche market to cater to.
When you list merchandise on eBay try putting two or three really good pictures of the item with your listing. If possible, try to crop the picture to eliminate everything but the item that you are selling. It makes you look more professional. You should also list as much information as possible. If you know a lot about a hobby or subject, use that knowledge. Customers appreciate knowledgeable sellers. Here is the best stuff to sell on eBay.
Paperback Books - They’re small, they don’t weigh that much, and you can ship them through USPS Media Mail. They can even be shipped all over the world for no extra cost using eBay’s Global Shipping Program. I’ve had the best luck with classic science fiction from the 1960s and 70s, movie-tie books, mysteries and series books such as Doc Savage.
Cookbooks - The older or more unusual a cookbook is the better. Cookbooks from the 1940s, ’50s and ’60s aren’t that hard to find and sell well. Weird and nostalgic cookbooks and country cooking books are big sellers. Even the cookbooks sold with appliances sell.
How to Books - Old how-to books, especially those related to carpentry and tools sell well. Those old Popular Science and Popular Mechanics do-it-yourself books also sell well.
Comic Books- Even though the comic book market has collapsed, there is still a lot of demand for certain titles. Marvel Comics sell better than DC. Right now, there’s quite a bit of demand for Marvel superhero titles from the 1980s, particularly Spiderman, Captain America, the Avengers and classic Marvel titles from the 1960s. When you sell a comic book, always list the names of the writer and artist. Comics with the first appearance of a popular supervillain sell best.
James Bond - Agent 007 is still as popular as ever. James Bond books from the 1960s sell quickly. The movie-tie paperbacks and hardbacks sell well, and so do the 1960s hardback books. There is also a huge demand for Bond paperbacks from the 1960s. Any Bond book with a picture of one of the actors from the movies on it will sell. Even Timothy Dalton has a lot of loyal fans.
Local and Regional History -There is a great demand for local and regional history books. Many are published in small numbers and can be hard to find. Items published by museums and historical societies are also in demand. Genealogists and amateur historians are always looking for local history. They will even pay for pamphlets published by small-town historical societies.
Disney - The real magic at the Magic Kingdom is its ability to make money. There are lots of collectors looking for Disney children’s books and anything related to Disneyland and Walt Disney World. I listed a 20th Anniversary of Walt Disney World coffee table book and it sold within three days.
Software - There is a big market for brand name software from major makers such as Microsoft and Adobe. Adobe products, such as Photoshop and Acrobat, sell very well. If software is unopened, it will sell even faster. I sold a 10-year-old copy of Microsoft Front Page that was in the original wrapper for $50.
Watches - Watchmaking is a popular hobby and the supplies for it are some of the best stuff to sell on eBay. Pocketwatch cases are in demand from watchmakers and fans of Steam Punk (hobbyists who like to dress up in pseudo Victorian clothes). I made several hundred dollars by selling a batch of old watchmaking equipment my dad had kept in the shed for years.
Cameras and camera equipment - There is a large demand for classic film cameras. Lenses sell best, but so do old film cameras from the 1940s or ’50s. American and German-made cameras sell well. I even made $50 selling a broken Nikon from the early 1990s.
