Character and collecting appeal

Beasts are one of the classic monster Types of the original series.

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 SDK-004. The code SDK-004, without a language letter, marks the original North American printing. European English copies have an E in the code, such as SDK-E004, and are priced separately. It is the Common version. Commons have a plain name and no foil. Starter Deck: Kaiba has one other printing of The Wicked Worm Beast: SDK-004 (€0.45). 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 €3.00 and a PSA 10 for €74.87. Our monthly prices for it go back to October 2021. Over the last 12 months ungraded copies are up 52%, and down 20% in the last month. Its highest monthly ungraded value was €6.69 in October 2021, 55% above today. PSA 10 copies have moved sideways over the same 12 months. 1st Edition copies sell for about 6.7× the Unlimited printing (€3.00 against €0.45).

Grading and population

A PSA 10 sells for 25× the ungraded price. That gap is big enough that grading a sharp, well-centred copy can pay for itself. On cards from the early 2000s, the dark brown backs show every scuff and white edge, so top grades are scarce.

Investment potential

In its favour: steady demand, with ungraded prices up 52% in a year; a price well below its October 2021 peak, which some collectors see as room to recover; it comes from the 1st Edition run of an early English set, which will never be printed again; an active market (29 recent completed sales), so it is easy to sell. Treat this as background, not a prediction or financial advice.

Before you buy

Expect to pay around €3.00 for a clean ungraded copy; played copies sell for less. Ask the seller to show the code SDK-004, the "1st Edition" text and the Common finish clearly in the photos, as listing titles often mix up printings. Cards from 2002 often show white wear on the back edges and corners, so ask for photos of the back before you buy.
