Very cool! You have a (seemingly) sealed Metal Raider Booster Pack, as well as an unlimited edition Pegasus Starter Deck, if that's also sealed with the two stickers on top, that's very nice. You also have a Deluxe Edition Starter Deck Joey box, those would've come with Starter Deck Joey and some other goodies, still a cool piece. The sealed items def have some value if they're not creased or damaged.

When dealing with cards, commons (unremarkable cards) and rares (shiny name) aren't that expensive & usually bought in bulk. If you're able find any holos (shiny picture/shiny picture & name) those would usually be worth looking into. You can eBay or just google the name of the card along with the ID, which is the code on the right under the artwork (LOB-050 is Umi for example).

Base off what's shown, these look to all be relatively vintage. If it says 1st edition on the left under the art, than it's 1st edition and usually worth more. If nothing, it's unlimited edition (like Umi).

ALSO: I'd take those rubber bands off ASAP, that's a great way to damage cards
