Quoted from Haymaker:
Sell it bro. I am currently piecing out my collection (sorry all my TG and Saturn stuff is long gone, hot market) and its nice to let go. Part of me wants to hold onto things but every time I sell a piece that was really special to me it only stings until its sold, and then I feel fine. I'm sure one day I'll be kind of sad I sold all the stuff but when you have an entire room dedicated to NES/SNES/Genesis ect, and you never use any of it, whats the point? Ideally I'll use the money to buy more pins. Its a lot easier and more convenient to sell a couple pins than hundreds or thousands of games, I can tell you that much.
I kind of wish a kept a few things over the years but that kind of stuff just sits in boxes in closets. I sold a bunch of old collectibles earlier this year. Felt great to clear out piles of stuff and get good money in return.
