How much are these yu-gi-oh cards worth?

why don't you check online? check the yugioh wiki for info on rarities, becaue theinin is an ultra rare, and B.L.S., the M.B., and relenquished might be secret rare. if only the picture is shiny, its a super rare. if only the name is shiny, its a rare. if both, ultra rare. from there, the picture gets different, so look that up. seiyaryu sounds like a secret. ultimate obedient fiend is just a common, so it wont be worth as much. but just google the card's names online, or compare prices on ebay, because you can really make some money on rare cards
