Version and identification

This guide covers the 1st Edition printing. The words "1st Edition" are printed below the artwork on the left; copies without them are the Unlimited printing and usually sell for less. Check the code printed below the artwork on the right: it should read LON-028. The code LON-028, without a language letter, marks the original North American printing. European English copies have an E in the code, such as LON-E028, 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 Jam Defender: LON-028 (€0.80), LON-E028, LON-E028 1st Edition and LON-EN028. 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 €4.22, a PSA 9 for €47.58 and a PSA 10 for €228.26. Our monthly prices for it go back to February 2022. Over the last 12 months ungraded copies are up 58%, and down 17% in the last month. Its highest monthly ungraded value was €5.08 in August 2026, 17% above today. PSA 10 copies have moved up 60% over the same 12 months. 1st Edition copies sell for about 5.3× the Unlimited printing (€4.22 against €0.80).

Grading and population

A PSA 10 sells for 54.1× the ungraded price and 4.8× 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 58% in a year; it comes from the 1st Edition run of an early English set, which will never be printed again; an active market (30 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 €4.22 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €47.58. Ask the seller to show the code LON-028, the "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.
