The good news is that another extension of the MOU with Italy did not mean another expansion of the designated list. Greek, Etruscan and early Roman Republican and city coins remain restricted, but Roman Imperial coins may still enter the US without cumbersome (and most often unobtainable) paperwork.
There was a concern that there might be a move to expand the list given the breadth of the designated list for Bulgaria, but it seems common sense (helped along by the overwhelming number of public comments) prevailed.
CPO thanks anyone who commented back in April to CPAC. The effort to keep Roman Imperial coins off the designated list was a successful one.
