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-015. The code LON-015, without a language letter, marks the original North American printing. European English copies have an E in the code, such as LON-E015, and are priced separately. It is the Short Print version. Short Prints look like Commons but were printed in smaller numbers. Labyrinth of Nightmare has 4 other printings of Mask of Weakness: LON-015 1st Edition (€3.14), LON-E015, LON-E015 1st Edition and LON-EN015. Each has its own price, so match the code, edition and rarity exactly.

Price history

Today an ungraded copy of this printing sells for about €0.95, a PSA 9 for €7.13 and a PSA 10 for €71.09. Our monthly prices for it go back to October 2021. Over the last 12 months ungraded copies are down 34%, and up 83% in the last month. Its highest monthly ungraded value was €2.03 in May 2024, 53% above today. PSA 10 copies have moved down 14% over the same 12 months. 1st Edition copies sell for about 3.3× the Unlimited printing (€3.14 against €0.95).

Grading and population

A PSA 10 sells for 74.8× the ungraded price and 10× 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: a price well below its May 2024 peak, which some collectors see as room to recover; it comes from the first years of the English game, which are no longer printed; an active market (25 recent completed sales), so it is easy to sell. Against it: falling prices, down 34% in a year. Past prices do not guarantee future ones. This is not financial advice.

Before you buy

Expect to pay around €0.95 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €7.13. Ask the seller to show the code LON-015, the missing "1st Edition" text and the Short Print 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.
