Character and collecting appeal
Wyrms are a modern Type with eastern dragon designs. Its effect centres on clearing the field, banishing cards and Special Summoning. Its once-per-turn limits are typical of modern card design. It cannot be Normal Summoned, so it has to be brought out by its own conditions.
Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN023. RA03-EN023 is the English printing. Other languages use their own letters in place of EN, such as DE or FR, and are priced separately. It is the Quarter Century Secret Rare version. Quarter Century Secret Rares were introduced for the game's 25th anniversary.

Price history
Today an ungraded copy of this printing sells for about €0.29, a PSA 9 for €5.35 and a PSA 10 for €53.50. Our monthly prices for it go back to November 2024.

Grading and population
A PSA 10 sells for 184.5× the ungraded price and 10× a PSA 9. That gap is small, so grading fees may outweigh the gain unless the card is for your own collection. Even pack-fresh modern cards can have surface scratches or curling foil, so a 10 is never guaranteed.
Investment potential
In its favour: a price well below its June 2025 peak, which some collectors see as room to recover; an active market (26 recent completed sales), so it is easy to sell. Against it: falling prices, down 96% in a year; large modern print runs, which tend to cap prices unless a card becomes iconic. Treat this as background, not a prediction or financial advice.
Before you buy
Expect to pay around €0.29 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €5.35. Ask the seller to show the code RA03-EN023 and the Quarter Century Secret Rare finish clearly in the photos, as listing titles often mix up printings. Modern foils can be scratched or curled straight from the pack, so check the surface under a light if you plan to grade.
