Received this Burning Shadows Charizard GX rainbow rare in a PSA 10 and the front looks amazing with the texturing. Only downside is the back has whitening on the corners which is quite noticeable and makes it a weak-ish psa 10 compared to others I’ve seen sold. I know this is basically a modern grail for charizard and the set has bad quality issues. Still worth holding or sell for $5k buyback?
