When I found out we’d be moving frequently (around 2018) I decided to sell my hoard of video game strategy guides, Nintendo Power issues, and sealed collector’s editions of video games, I sold them all on Ebay within two months and made over 5,000 dollars. I got so used to using my packing tape roller and listing stuff on Ebay. It’s easier than you think and it helps you build up a lot of good ratings as a seller.
I still have lots of strategy guides but most are under the 20 dollar range so I haven’t bothered, but I’m getting desperate and considering starting up to sell again. I wager I could get 500-600 dollars from what I have left in the garage.
I sold my Earthbound cartridge paired with the Strategy Guide that came with it for 300 bucks a few years back. I got a SNES mini that has it and just use the online guides for it instead.
