Character and collecting appeal

Fiends are one of the largest Types in the game, home to many of its darker and more unusual designs. Its text names Curse of the Masked Beast, so collectors often look for them together. Curse of the Masked Beast mentions The Masked Beast in its 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 LON-001. The code LON-001, without a language letter, marks the original North American printing. European English copies have an E in the code, such as LON-E001, and are priced separately. It is the Ultra Rare version. Ultra Rares have a gold-foil name and holographic artwork. Labyrinth of Nightmare has 4 other printings of The Masked Beast: LON-001 1st Edition (€33.66), LON-E001, LON-E001 1st Edition (€24.88) and LON-EN001. Each has its own price, so match the code, edition and rarity exactly.

Grading and population

A PSA 10 sells for 17.9× the ungraded price and 3.5× a PSA 9. That gap is big enough that grading a sharp, well-centred copy can pay for itself. Early English Yu-Gi-Oh! cards often have off-centre cuts and wear on the dark brown back borders, which is why high grades are hard to reach.

Investment potential

In its favour: steady demand, with ungraded prices up 19% in a year; it comes from the first years of the English game, which are no longer printed; an active market (69 recent completed sales), so it is easy to sell. Card prices can fall as well as rise, so this is not financial advice.

Before you buy

Expect to pay around €6.93 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €35.56. Ask the seller to show the code LON-001, the missing "1st Edition" text and the Ultra Rare finish clearly in the photos, as listing titles often mix up printings. Cards from 2003 often show white wear on the back edges and corners, so ask for photos of the back before you buy.
