Topps retailer Finest Star Wars trading cards 2018

Product Name: Topps retailer Finest Star Wars trading cards 2018
I clearly opened these packs. However that's all retailer I did just to see the cards just once. They have been in box since then. Notice one box has more cards than the next. When I opened these boxes I also opened (and ruined) another box of Star Wars cards. So I mixed them. I didn't think I'd sell these so I didn't think much of it. Think of it as a bonus. The original set sells for about, roughly, $350 brand new. Based off that price and the fact that you're getting extra from a set where I'm not clear of it's value, is where I come up with my price. I'm not a collector of cards, so forgive me for lack of information.
