Not exactly the same. First he (or his mother) bought an advertised item as teacups. If it was labeled "teacups and S&W revolver" then there would be no problem as everyone knew what was being sold.
As far as the example of buying books then finding a first edition, that is not a problem. You were buying a box of books, and nothing else.
I guess it boils down to how he feels about it. If his is not bothered by it, then there is nothing we can say to change his mind.

Suppose it was a box of books that he bought for $10. Upon going through it he found that one of the books was a rare first edition worth thousands. Would anybody be saying there is some duty to "go back to the estate" and ask if they really wanted to sell it as cheaply as they did?
In the context described - professional liquidation of an estate - I think the correct answer is that if the liquidator offers a box for $10, then ten bucks gets the buyer whatever is inside. Period. If there's a diamond ring in there, you've got a $10 diamond ring. Same thing if there's a gun. The estate owners had a chance to go through and evaluate all the stuff before handing it over to the estate liquidator. The liquidator also had a chance to check the goods they were offering, and see if there were any hidden "finds" in the various lots being offered.
If both parties failed to do so and thereby overlooked something of greater value (a rare book, a nice gun, a diamond ring) in a box they thought held stuff of lesser value, they should be the ones to bear the "loss" of not getting as much for their stuff as they might have if they'd been more diligent. I see absolutely no reason for a buyer to have the slightest remorse for finding and keeping anything they bought through the estate liquidation process.
