Though I can't be sure of course, I don't think Atlas bought them as they have got a good eye for copper that they can buy at reasonable prices, mark up strongly and still sell, so eg coronets at what would be $30k plus would feel like a stretch. Also I have never seen them risk buying unprecedentedly really expensive copper ie none of the copper from Cope 1 has turned up on their website (which I check reasonably regularly) with the exception of that relatively cheap 1849. Recent earlier sky-high copper (eg 2023, 1699 halfpenny plus farthing ex Heritage) hasn't appeared with them either to my knowledge. They got the 1849 for a good price and if I'd hung around for it, I might have bid up to that figure if not more. It was less bright in the hand than the 1837 though.
