I have this card with an auto grade Gem Mint 10.

Just visited a local card shop in Sydney, and they said that to get a dual grade, I would need to crack the current slab, then send it PSA Express Auto (25 business days turnaround) so that I could have it back for the World Cup.

I am in 2 minds. Do I crack and submit for dual grade, potentially damaging the card or losing the gem mint auto certification. Or just leave it the way it is and sell it as is??? Any help will be appreciated.
