Rob Baillie, from sellmymobile.com who conducted the study, said; “Like most collectibles, how much something is worth often depends on how rare it is and what condition it’s in.
“But even as some more common machines get older, working examples are increasingly harder to track down which only increases their value. While functioning examples will be the most lucrative, some collectors will buy broken items to strip for parts.
“If you think that you might have a valuable PC or video games console at home, start by looking at similar examples that have recently sold on auction sites. Getting a feel for how much collectors are willing to pay will help you set a realistic price making for a quicker sale.
“However, if you’re lucky enough to have one of the rare items featured on our list then you might want to contact an expert first.
“Having a professional to value and authenticate your item could help dramatically increase the price potential buyers are willing to pay”.
Top tips for selling old tech online include;
1 Does it work? Working items sell for more. Plug it in or charge the battery and check everything is in order.
2 Do your homework. Look at the history of the item and how many were sold, to give you a better understanding when researching the going rate of comparable lots.
3 Be descriptive. A thorough description of your item could help increase buyer confidence while deterring opportunists.
4 Photos matter. Take a variety of well-lit photos from different angles while including closeups of components. Include honest photographs of any damage, even small cosmetic scuffs.
5 Check postage. Before settling on a price, get a quote for shipping and calculate your profit margin. Offering free shipping could help entice buyers.
