Professor Nathan Elkins has written an important post "Import Restrictions and Coins: Lobbying, Duplicity, and Ancient Egypt's Closed Currency System" (May 14, 2014). He notes that while archaeologists stress the importance of including coins in MOUs, coin collectors do not.
I should declare an interest in the topic as I published a short study of the Ptolemaic coins linked to Arsinoe in the Peloponnese (further information here).

Those coins from Arsinoe will have been protected already by the Greek MOU. The potential MOU with Egypt would protect coins struck in what is now modern Egypt and which are found in what is now Egypt.
I am sure that you would agree that the coins of Arsinoe-in-the-Peloponnese (Methana) would be covered by the MOU with Greece.
For the details of that MOU see here.
