Grading and population
A PSA 10 sells for 14.3× the ungraded price and 2.9× a PSA 9. That gap is small, so grading fees may outweigh the gain unless the card is for your own collection. Modern foils can leave the pack with scratches, print lines or a slight curl, so even fresh copies do not always reach a 10.
Investment potential
In its favour: an active market (25 recent completed sales), so it is easy to sell. Against it: falling prices, down 19% in a year; 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 €3.13 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €15.51. Ask the seller to show the code RA03-EN053 and the Ultra 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.
