While they are often called "gold cards" or "gold foil cards", the "gold" is actually a special foil printing that gives the cards a shiny, golden appearance.
Here's why:
* Cost: Real gold is extremely expensive, and using it for trading cards would be economically unfeasible.
* Durability: Real gold is soft and easily scratched, making it unsuitable for a collectible card that needs to be handled regularly.
* Appearance: The foil used in Pokemon cards is designed to mimic the look and feel of real gold, but it's a much more affordable and durable material.
So, the next time you see a "gold" Pokemon card, remember it's just a clever printing technique, not actual gold!
