The US Government has repatriated several valuable coins produced in Greece millenia ago to that country as part of a plea deal agreed to by prominent collector Peter Weiss.
There is no suggestion that the coins that have been repatriated were "stolen" from Greece. Rather, it appears that the only basis for their repatriation was that they were produced in ancient cities now located in that modern nation state and that they were on Dr. Weiss' person at the time of his arrest on an unrelated charge.
So, is this an example of good police work or rather of how culture cops can and do use the threat of criminal conviction to force the repatriation of objects with little regard to concepts of private property that are supposed to be enshrined in our Constitution?
And what of the coins themselves? Will the bankrupt, modern nation state of Greece be a better steward for their care than American collectors? One really wonders.
