Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN053. RA03-EN053 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.

Grading and population
A PSA 10 sells for 7.9× the ungraded price and 1.6× a PSA 9. That gap is big enough that grading a sharp, well-centred copy can pay for itself. Even pack-fresh modern cards can have surface scratches or curling foil, so a 10 is never guaranteed.
Investment potential
In its favour: an active market (25 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 €12.65 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €62.62. Ask the seller to show the code RA03-EN053 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.
