Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN153. RA03-EN153 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. Quarter Century Bonanza has one other printing of Elemental HERO Thunder Giant: RA03-EN153 Quarter Century Secret Rare (€7.49). 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 €2.32, a PSA 9 for €10.50 and a PSA 10 for €39.01. Our monthly prices for it go back to November 2024. Over the last 12 months ungraded copies are up 31%, and up 7% in the last month. Its highest monthly ungraded value was €2.66 in November 2024, 13% above today. PSA 10 copies have moved up 3% over the same 12 months.
Grading and population
A PSA 10 sells for 16.8× the ungraded price and 3.7× 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: steady demand, with ungraded prices up 31% in a year; an active market (26 recent completed sales), so it is easy to sell. Against it: 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 €2.32 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €10.50. Ask the seller to show the code RA03-EN153 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.
