Left Arm of the Forbidden One [Misprint] #LOB-123 collector guide

About Left Arm of the Forbidden One

Left Arm of the Forbidden One is a Normal Monster, with flavour text instead of an effect, printed as LOB-123 in Legend of Blue Eyes White Dragon (2002) as an Ultra Rare. It is a Level 1 DARK Spellcaster monster with 200 ATK and 300 DEF. Legend of Blue Eyes White Dragon was the first booster set of the English Yu-Gi-Oh! Trading Card Game. It brought Blue-Eyes White Dragon, Dark Magician, Red-Eyes Black Dragon and the five pieces of Exodia to English-speaking players, so almost every card in it is a piece of the game's history. Ungraded, this printing ranks 18th of the 454 Legend of Blue Eyes White Dragon cards we track. The top card is Blue-Eyes White Dragon at €968.32.

Character and collecting appeal

It is one of the four limb pieces of Exodia. Holding all five pieces in your hand wins the duel, and full sets in the same edition and printing sell for more than the pieces on their own. As a Normal Monster it is collected for its artwork and its spot in the set rather than for play. Contract with Exodia, Exodia Necross and Exodia the Forbidden One mention Left Arm of the Forbidden One in their text, which keeps it relevant.

Version and identification

This guide covers the Unlimited printing, without the "1st Edition" text below the artwork. 1st Edition copies of the same card have their own, usually higher, prices. Check the code printed below the artwork on the right: it should read LOB-123. The code LOB-123, without a language letter, marks the original North American printing. European English copies have an E in the code, such as LOB-E123, and are priced separately. It is the Ultra Rare version. Ultra Rares have a gold-foil name and holographic artwork. This is a misprint, priced separately from correctly printed copies. Make sure the listing photos show the error. Legend of Blue Eyes White Dragon has 4 other printings of Left Arm of the Forbidden One: LOB-123 (€14.28), LOB-123 1st Edition (€151.25), LOB-E100 (€15.81) and LOB-E100 1st Edition (€40.66). Each has its own price, so match the code, edition and rarity exactly.

Before you buy

Expect to pay around €110.95 for a clean ungraded copy; played copies sell for less. Ask the seller to show the code LOB-123, the missing "1st Edition" text and the Ultra Rare finish clearly in the photos, as listing titles often mix up printings. At this price fakes are worth checking for: genuine cards have a small holographic seal (the Eye of Anubis) in the bottom-right corner, and the font, colours and card back should match a copy you know is genuine. Look up the certificate number of any graded copy on the grading company's website. Cards from 2002 often show white wear on the back edges and corners, so ask for photos of the back before you buy.
