davidcyclebackIf you cut it up and got PSA10s and PSA9s, you might increase the value. If you get PSA5s, PSA6s or even PSA7s, or PSA Authentic as they're recently cut, you've probably lowered the value substantially. Financially, I would think the best bet would be to leave it in tact. Personally, I wouldn't roll the dice that a machine would produce Mint cards from the sheet, especially considering PSA and SGC might not grade them as Mint anyway.
