Sorry to revive an older thread, but this is the only conversation I could find and it didn't look like a conclusion had been found. Has the mystery of the slightly off coloured pcb boards been solved? I have a damaged dragonite which I use as a benchmark. My whole collection matches it except US keldeo, meloetta, y90E along with EUR y90p, y90z.
I recently contacted a seller about their personal collection and their meloetta and y90e match mine, but their keldeo is a different shade while all 3 of mine match. This just raises more questions.
Any help would be greatly appreciated.
