RKT Grading is based in the UK. Here's why One Piece collectors choose us instead of shipping cards overseas.
One Piece is one of the youngest major TCGs, so most cards in circulation are still near-mint. That makes the gap between a 9 and a 10 even more important. It's the detail that separates your card from thousands of identical copies.
With most One Piece cards in near-mint condition, the gap between a 9 and a 10 is tiny. Our grading technology spots details the naked eye misses, so every card gets the grade it deserves.
Your cards never leave the UK. No customs charges, no import VAT and no 3-6 month waits. Cards come back in 2-10 working days.
Every slab has an NTAG 213 NFC chip linked to the card's certificate. Tap your phone to verify the grade is legit. No app required.
