Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN007. RA03-EN007 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 Collector's Rare version. Collector's Rares have a textured holographic finish over the artwork and frame.

Grading and population
A PSA 10 sells for 24× the ungraded price and 4× 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
Against it: large modern print runs, which tend to cap prices unless a card becomes iconic. Past prices do not guarantee future ones. This is not financial advice.
Before you buy
Expect to pay around €1.47 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €8.92. Ask the seller to show the code RA03-EN007 and the Collector's 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.
