One prime example of a collector who cashed in big time is Charles Amble. The American video game enthusiast from Wisconsin sold his collection of 750 Nintendo games (some are shown here) on eBay in 2017, earning him a total of $20,000 – the equivalent of almost $26,000 (£19k) in today's money.
Amble had been collecting video games since childhood and had picked up the majority of them from garage sales, Goodwill stores, and auctions.
"It’s kind of a nerdy hobby that a lot of people who are my age, you know, that grew up in the late 80s, early 90s, can appreciate", Amble told news outlet WISN, adding that he planned to travel and possibly buy a boat with his profits.
