* Card Condition: The condition of the cards matters immensely. A mint condition, first edition Exodia set would be worth far more than a heavily played, damaged set.
* Rarity: Are these common printings or rare ones? First editions, limited edition, or even specific promotional printings can drastically affect value.
* Market Demand: The price of any collectible fluctuates based on demand. If Exodia is highly sought after at the moment, the price will be higher.
Instead of a price, here's how to find a reasonable value:
1. Check Online Marketplaces: Use websites like eBay, TCGplayer, or Troll and Toad to see what similar Exodia sets are selling for. Filter by condition and rarity to get a more accurate estimate.
2. Consult a Card Price Guide: Guides like "The Beckett Grading Services" or "Price Charting" can offer professional valuations, although these often focus on graded cards.
3. Ask Local Game Stores: Talk to your local game stores or card shops. They often have knowledge of local pricing and market trends.
Remember, a "reasonable" price is subjective. You need to consider your own needs, the card condition, and the current market before making a decision.
