As I said; you've hit the rough edge of keeping hobby items a secret.
Now; most people will know how expensive those cards are AND you won't get the Grove reasonably to finish your set,
But let's be honest as well; aren't you also partially upset at yourself for YOU could have been the one to cash in big time:

$30K without juice and counting. Not a bad day and as has been spoken; the consigner is thrilled.

P.S. And as for the rest of your secrets, as has been pointed out, better make sure you tell your children for otherwise when that day comes they might not even care about daddy's cards
