I was finally able to talk to an customs officer. The phone contact number provided in the detention letter of May 5th, (718) 553-2727, was incorrect. The correct phone number is (718) 487-2727. Also, it seems that one or more of the documents that I sent were misplaced, so I emailed them, along with the certified mail receipts to CBP today in the hope that they will be find their way to the review team. As of today, the coin is in Washington, DC for evaluation. By whom I am not sure. I cc'd Peter Tompa, and he send to me a ACCG newsletter link regarding new restrictions on the importation of certain coins from Turkey. https://accguild.org/news/10663710 We do, indeed, live in interesting times.
