Ryu Kokki [1st Edition] #IOC-090 collector guide

About Ryu Kokki

Ryu Kokki is an Effect Monster, printed as IOC-090 in Invasion of Chaos (2004) as a Common. It is a Level 6 DARK Zombie monster with 2,400 ATK and 2,000 DEF. At its Level it needs one Tribute to Normal Summon. Its ATK is the 10th highest of the 67 monsters in the set. Invasion of Chaos, released in 2004, brought Black Luster Soldier - Envoy of the Beginning, Chaos Emperor Dragon - Envoy of the End and Dark Magician of Chaos. The Envoys went on to dominate competitive play, which makes it one of the most important sets of the early game. Ungraded, this printing ranks 75th of the 224 Invasion of Chaos cards we track. The top card is Black Luster Soldier - Envoy of the Beginning at €143.91.

Character and collecting appeal

Zombies are built around the Graveyard, bringing monsters back again and again. In play, it is a card for destroying cards.

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 IOC-090. The code IOC-090, without a language letter, marks the original North American printing. European English copies have an E in the code, such as IOC-E090, and are priced separately. It is the Common version. Commons have a plain name and no foil. Invasion of Chaos has one other printing of Ryu Kokki: IOC-090 (€0.66). 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 €1.22, a PSA 9 for €8.02 and a PSA 10 for €77.28. Our monthly prices for it go back to February 2022. Over the last 12 months ungraded copies are down 12%, and up 44% in the last month. Its highest monthly ungraded value was €2.08 in February 2022, 41% above today. PSA 10 copies have moved up 13% over the same 12 months. 1st Edition copies sell for about 1.8× the Unlimited printing (€1.22 against €0.66).

Grading and population

A PSA 10 sells for 63.3× the ungraded price and 9.6× 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 February 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 (25 recent completed sales), so it is easy to sell. Against it: falling prices, down 12% in a year. Treat this as background, not a prediction or financial advice.

Before you buy

Expect to pay around €1.22 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €8.02. Ask the seller to show the code IOC-090, the "1st Edition" text and the Common finish clearly in the photos, as listing titles often mix up printings. Cards from 2004 often show white wear on the back edges and corners, so ask for photos of the back before you buy.
