No more old junk
Turn old into gold is the motto for Lego toys, for example. Particularly high prices can be achieved for complete sets from the Star Wars series, but also for Lego Technic.
From phonecards to exercise egg figures
Do you remember the telephone cards? Nobody needs them anymore. But they are very popular with collectors. If the cards are unused, their face value can even triple. Sites such as www.rummler.de contain all the information on the different series, including all variants and illustrations.
Surprise egg figures, especially from the 1970s and 80s, are also a collector's hit. Particularly popular: the Smurfs (worth up to approx. 1,500 euros).
And even if your offspring's passion for stickers has got on your nerves, there's nothing like the sense of achievement of a complete Panini collector's album. A well-preserved copy of the 2014 World Cup has a good chance of increasing in value over the next few years. One from the 1974 World Cup sells for around 450 euros today.
Comics by Donald Duck and Mickey Mouse as well as funny paperbacks from the Disney series are also in high demand.
More than 100 euros for a used smartphone
Electronic devices are also treasures that can be worth selling online. For example, the average eBay resale price for an iPhone 5s is 300 euros, and 270 euros for a Sony Playstation 4! A practical buying platform for electronics, CDs, DVDs and books is www.rebuy.de.
The largest online bazaar for all everyday items is www.ebay.de. Here you can offer your items at a fixed price or as an auction. Menu navigation and uploading pictures are very easy.
