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.

Grading and population
A PSA 10 sells for 14.7× the ungraded price and 3× 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 21% in a year; 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. Treat this as background, not a prediction or financial advice.
Before you buy
Expect to pay around €2.89 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €14.36. Ask the seller to show the code RA01-EN028 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.
