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 MRD-020. The code MRD-020, without a language letter, marks the original North American printing. European English copies have an E in the code, such as MRD-E020, and are priced separately. It is the Common version. Commons have a plain name and no foil. Metal Raiders has 3 other printings of Roaring Ocean Snake: MRD-020 (€0.95), MRD-E020 (€1.95) and MRD-E020 1st Edition (€3.27). 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 €2.14, a PSA 9 for €14.80 and a PSA 10 for €62.53. Our monthly prices for it go back to January 2022.

The most valuable is Metal Raiders MRD-E020 1st Edition at €3.27. 1st Edition copies sell for about 2.3× the Unlimited printing (€2.14 against €0.95).

Grading and population

A PSA 10 sells for 29.2× the ungraded price and 4.2× a PSA 9. 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: a price well below its March 2022 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 (40 recent completed sales), so it is easy to sell. Against it: falling prices, down 46% in a year. Treat this as background, not a prediction or financial advice.

Before you buy

Expect to pay around €2.14 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €14.80. Ask the seller to show the code MRD-020, 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.
