SDY-003 Winged Dragon, Guardian of the Fortress #1 Yu-Gi-Oh! Card

Our software checks the price of every English YuGiOh card ever issued and updates the guide price every week on Saturday night, so you can be sure that the price our guide gives you is 1) most recent and 2) statistically correct.

We publish prices for mint YuGiOh cards only, so if you are buying or selling used YuGiOh cards, you need to discount them accordingly. Our Guide Price is calculated by checking YuGiOh cards prices of recognised YuGiOh card dealers then dividing this to give you a weekly average price. If you're an individual, rather than a large YuGiOh dealer, who is looking sell YuGiOh cards on eBay, you can estimate the value of cards for selling approximately at our Guide Price minus 20-30%. For buying YuGiOh cards on eBay, you can also look for a bargain and find a YuGiOh card much cheaper than Guide Price (that's the beauty of eBay). Check seller’s feedback though and make sure you are buying mint YuGiOh cards and not some random lots!
