Ungraded, this printing ranks 449th of the 587 25th Anniversary Rarity Collection cards we track. The top card is Ghost Belle & Haunted Mansion at €51.83.
Character and collecting appeal
Fiends are one of the largest Types in the game, home to many of its darker and more unusual designs. Its text is about drawing cards and discarding. Its once-per-turn limits are typical of modern card design.
Version and identification
Check the code printed below the artwork on the right: it should read RA01-EN043. RA01-EN043 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 Platinum Secret Rare version. Platinum Secret Rares are a newer Secret Rare variant with a platinum-coloured finish. 25th Anniversary Rarity Collection has 8 other printings of Knightmare Unicorn: RA01-EN043 Alternate Art Quarter Century Secret Rare (€6.48), RA01-EN043 Alternate Art Ultimate Rare (€2.35), RA01-EN043 Collector's Rare (€1.89), RA01-EN043 Quarter Century Secret Rare (€2.91), RA01-EN043 Secret Rare (€0.45) and RA01-EN043 Super Rare (€1.08), and more. Each has its own price, so match the code, edition and rarity exactly.

Grading and population
A PSA 10 sells for 31.5× the ungraded price and 4.6× 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 November 2023 peak, which some collectors see as room to recover; an active market (25 recent completed sales), so it is easy to sell. Against it: falling prices, down 57% in a year; large modern print runs, which tend to cap prices unless a card becomes iconic. Card prices can fall as well as rise, so this is not financial advice.
Before you buy
Expect to pay around €1.03 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €7.13. Ask the seller to show the code RA01-EN043 and the Platinum 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.
