Anticipating what will make you money on eBay is a tricky art to perfect. A rare Funko Pop! can net $6000, while the Princess Diana Beanie Baby you've been holding onto since the 1990s might be worthless. One way to know what eBay buyers are after is to look at the site's best-selling categories. According to eBay sales data, these are the top six categories for making big bucks:

  1. Collectible cards: Worth up to $400,000
  1. Comic books: Worth up to $3.2 million
  1. Watches: Worth up to $535,500
  1. Designer handbags: Worth up to $88,000
  1. Luxury cars: Worth up to $500,000
  1. LEGOs: Worth up to $10,000

Collectible cards are some of the most valuable items on the site, with 500 cards earning sellers $10,000 or more since September 2018. In February 2019, a 1997 Michael Jordan basketball card sold for $350,100, and that same month, an autographed 2000 Tom Brady football card sold for $400,100.

When sifting through your old card collection, look out for other lost treasures from your childhood. There's a high demand for comic books on eBay: In 2014, Superman's inaugural comic Action Comics #1 sold for a record-breaking $3.2 million. And if you have rare LEGO sets around the house, they could be worth upwards of $10,000.

Second-hand luxury items are also worth a small fortune on eBay. A watch is purchased every 5 seconds on the website, and some are auctioned off for over half a million dollars. Handbags from designer brands are also sought after, with one Hermes Birkin bag selling for $88,000 in 2017. Of course limited-edition, luxury cars are valuable, but owners might not know they can find enthusiastic buyers on eBay. In 2018, a 2017 Lamborghini Aventador LP750-4 SuperVeloce was purchased from there for $499,900.

The categories above represent eBay's top moneymakers, but these are just a few examples of old items that can earn you extra cash. If you have an old VHS collection at home, here are the most valuable tapes to look for.
