pokemon cards (advice needed)

Images 3143-3152 are most likely fake cards. If you research in the Pokemon Company's card database what Rainbow Rare, V/VMAX, etc., look like, you will notice that they look very different from those. For example, Rainbow rare backgrounds are lighter than those, and no V cards have pure white backgrounds. Some people like to buy fake cards on purpose, but I don't know much about that market, so you'd have to research it. Just make sure you tell potential buyers they're fake so you don't scam someone by mistake!

Images 3135-3142 look real to me, but none of them are really worth much. Value is based on condition, rarity, and popularity of the character. Umbreon and Charizard are really the only characters that are so super- popular that their high rarity- cards are worth a lot of money. For example, the Rainbow Rare Rillaboom in image 3135 is very rare, but most people don't care about Rillaboom enough for the card to still be worth much.

As a collector and player, I personally would keep a small number of the real cards because I think some of them are pretty and some of them have practical usage in decks. But if your only concern is resale value, then no, these aren't worth much… unless someone who is into fakes REALLY wants those fakes! Again, I don't know much about the market for fake cards, so you'll have to research that on your own.

You may want to bring your cards to an employee at a hobby store and have them appraised just in case I am wrong about some of them.
