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-E026. The E in LON-E026 marks the European English printing. The North American printing uses a code without the letter, sometimes with a different card number, and has its own prices. It is the Rare version. Rares have a silver-foil name and plain artwork. Labyrinth of Nightmare has 4 other printings of Jam Breeding Machine: LON-026 (€0.66), LON-026 1st Edition (€1.70), LON-E026 1st Edition (€8.39) and LON-EN026. Each has its own price, so match the code, edition and rarity exactly.

Investment potential

In its favour: it comes from the first years of the English game, which are no longer printed. Against it: thin trading, so selling quickly can mean accepting a lower price. Treat this as background, not a prediction or financial advice.

Before you buy

Expect to pay around €6.73 for a clean ungraded copy; played copies sell for less. Ask the seller to show the code LON-E026, the missing "1st Edition" text and the 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.
