What would you do???

Crack it, keep the flip and send it to PSA. Keep a scan of the card in the SGC holder and when you scan it the PSA holder, include the SGC flip.

Since the card is as rare as you say, and if you were to choose Beckett, it's very possible they would deem it fake due to lack of experience with that issue.

BTW, I'm not sure if PSA would return your SGC flip.

Maybe we should start a thread showing flips from cracked slabs for more accurate reports?

I know BVG gets a bad rap in the vintage world, but honestly their holders are indestructible. You cannot break one if you tried. And even when you try, it's still tough.

I've had SGC and PSA holders fall apart in simple instances like dropping the card on the ground. So if your number 1 priority is securing the card, I'd go with BVG.
