Article: All genuine Yu Gi Oh! cards feature rounded edges at the corners of the card. If the card has pointed or angled corners, then it's a counterfeit card. Be wary of cards that have corners that are rounded off too much as well. The texture of the surface of the card should feel glossy and slightly raised to reflect the features in the art. Rub the surface of the card with your fingertip to feel the texture of it. Fake cards are often flat and rough. Fake cards may feel like sandpaper when you rub it. A major tell-tale sign of a fake card are borders on either the front or back of the card that aren't even and consistent. It's a sign that the card was miscut and is a counterfeit. Make sure you check both the front and back of the card for an uneven border. Authentic cards will have a shiny, square stamp on the bottom right corner of the front of the card with the words "Yu-Gi-Oh!" in small, horizontal script. Fake cards may be missing the foil stamp or the letters may be arranged vertically. The color of the foil should be either gold or silver. Any other color is a counterfeit. The back of the card should have a dark orange swirl with a black oval in the center. On the bottom right hand corner there should be the official Yu Gi Oh! logo. It should also say "trading card game" with a trademark symbol. If any of the features are missing or in the wrong location, then the card is fake. The border on the back of the card should be slightly thicker than the border on the front of the card as well.

What is a summary?
Look for rounded corners on the card. Feel the surface of the card with your finger to check the texture. Check to see if the borders of the card are miscut. Inspect the foil stamp in the bottom right corner of the card. Confirm the design, logo, and trademark on the back of the card are correct.
