Looking to sell my Collector’s Edition for the Switch and not sure what’s a reasonable price

I have listed my Night in the Woods Collector’s Edition on EBay. There is a small cosmetic flaw on the box at the top of the box and I opened the game and the CDs but everything else is still wrapped up. I didn’t know how to price it so I looked at the other pricing there. Looks like brand new is going for around $600 or so, I priced mine for around $350 but I’m worried it might be the wrong pricing for it. I’m not a scalper, I’m a fan who needs to sell it. Could anyone tell me if I’m being reasonable in my pricing?
