All excellent cards
Gold Card: These are secret rare cards with a distinctive gold color scheme, often featuring a Pokmon, Trainer, or Energy card
The only desire Id have for a card like this, even if it were my favorite Pokemon/card, would be to profit by selling it off to someone who is actually captivated by the defect
The newest Pokemon and trainers are still very affordable, with some modern cards of classic Kantonian Pokemon also standing out among the best budget Pokemon TCG cards
