Unlimited Edition is the edition of cards that have no edition text in the TCG, Korean OCG, and Asian-English OCG. In the Japanese, Japanese-Asian, and Chinese OCG, cards are not printed with editions (other than Duel Terminal Edition), so cards lacking edition text are referred to as Standard Edition instead.
Once a card has finished its 1st Edition run, the cards are printed without edition text, referred to as Unlimited Edition; on very rare occasions, Limited Edition sets may have Unlimited Edition reprints. Additionally, some promotional cards and reprint sets are printed as Unlimited Edition, without having a print in another edition.
On Unlimited Edition cards, the Eye of Anubis Hologram is silver; on 1st and Limited Edition cards, it is gold.
On the secondary market, Unlimited Edition prints of cards are typically worth less than their equivalent 1st Edition print of the same rarity.
