[Questions] 1998 pokemon cards

Hello everyone n anyone :) so here's my problem. i have a bunch of 1998 pokemon cards and i know there worth some bucks. I went on TCGplayer.com to try n find the value of these cards only to be completely confused because of how many different cards they have made. base set , base set shadowless base set 1 with a flower base set 2 lol the list goes on. can anyone help me find how much these cards are worth? i have alot of cards. Japanese 1998 cards some are shiny (holo i think) PLEASE HELP :( thank you for your time to read and reply to this post . the pics here are just the Japanese cards and Machamp. i have a box full of 1998 cards. Promos. im trying to do this slowly due to haveing so many cards and not wanting to sell a single one intill i know the price and if its worth to get graded for more value. even tho the cards are in mint condition getting em graded adds waaaaay more value to the card
