Even if they did they wouldn't have been allowed to take them home. They would have had to have been smuggled out. And I think only a couple of them show actual circulation. I don't think "many" of them were recovered from circulation. A few of the Sac mules were found in circulation as well, but most of them were smuggled out and sold.
PCGS has 6 in MS61-63 and 6 in VF Details-AU58. NGC has 5 MS61-63 and 9 AU50-58. Some overlaps of course, but pretty close to "most" of them are circulated. OP coin sold for $336k with BP. I was way off.
You're likely right, but I'd like to think not as far as stolen. As for Karma, I would doubt it. If it was, that would be a bucket full.
