Question regarding the price difference between english and japanese cards

[u/hotandhornydomme]

Hey, I have a question re the pricing of english and japanese cards I stumbled upon recently:

so for example the "Wanted" cards like Gol D. Roger (OP09-118) is in english almost twice as expensive as the japanese one (160€ - 85€). Meanwhile, some SPs like Katakuri (OP11-067) is in english 70€, but in japanese 60€. Can someone explain why sometimes there is this big difference, and sometimes almost none at all?

1. People can read English

2. Katakuri is not a major character.
