I know nothing about Yu-Gi-Oh cards but found a bunch as we were cleaning out rooms. These are all at least 10 years old as they were my son’s in elementary school and now he’s off to college There are a few Hologram cards - Cyber Dragon Core, Machina Gearframe and Machina Peacemaker All in good shape. A few have some creasing Yu gi oh, trading cards, hologram, collectors, Y2K
