1. Set and Expansion:
* Look for the set symbol: Every set of Pokemon cards has a unique symbol. For example, the "Base Set" cards will have a red star, while the "Fossil" set has a fossil-shaped symbol.
* Check the card number: Each card within a set has a unique number. This can help you confirm which set it belongs to.
* Online Resources: Websites like PokeBeach or Bulbapedia have comprehensive lists of sets with images, release dates, and other helpful information.
2. Card Back Design:
* The back of the card changes: Each generation of Pokemon cards has a unique back design. Older cards have simpler designs, while newer cards have more detailed artwork and patterns.
* Look for the copyright date: The copyright date is typically printed on the bottom right corner of the back of the card. This can give you a general timeframe for the card's release.
3. Other Clues:
* Condition: Older cards are more likely to have wear and tear, such as scratches, creases, or faded colors.
* Cardstock: The thickness and texture of the cardstock can also indicate age. Older cards often have thinner and less durable cardstock.
* Holofoil: The way the holofoil (if any) appears can be a clue. Older holofoils tend to be less reflective and have a more "sparkly" look compared to newer holographic cards.
Important Notes:
* Reprints: Be aware that Pokemon has reprinted some older sets. Reprints will have a different copyright date and may have minor design changes.
* Fake Cards: Be cautious when trying to determine the age of cards, especially if they appear suspiciously perfect or are being sold at an unusually low price.
If you are unsure about a card's age or authenticity, it is always best to consult with a knowledgeable collector or a reputable card grading service.
