Version and identification
Check the code printed below the artwork on the right: it should read RA01-EN010. RA01-EN010 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 Ultimate Rare version. Ultimate Rares have embossed artwork, borders and card name. 25th Anniversary Rarity Collection has 7 other printings of Inspector Boarder: RA01-EN010 Collector's Rare (€1.57), RA01-EN010 Misprint (€8.40), RA01-EN010 Platinum Secret Rare (€0.39), RA01-EN010 Quarter Century Secret Rare (€4.27), RA01-EN010 Secret Rare (€0.24) and RA01-EN010 Super Rare (€1.47), and more.

Grading and population
A PSA 10 sells for 24.1× the ungraded price and 4.3× 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: an active market (22 recent completed sales), so it is easy to sell. Against it: falling prices, down 14% 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 €1.44 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €8.02. Ask the seller to show the code RA01-EN010 and the Ultimate 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.
