...the Turks might have some laws on antiquities that your Grandfather has circumvented...
They do. Turkish law states, and has stated since 1884, that any ancient artifact found in Turkish soil belongs to the State. However, prior to 1973, these laws were more of a philosophy than an actual prohibition, with very vague definitions on what an "antiquity" was and with little enforcement on the ground, particularly in regard to small, common, easily removable artifacts such as coins. The newer 1973 law is quite explicit about coins: any coins older than the reign of Ottoman Sultan Abdulmecid I (AD 1839) found in Turkish soil are illegal to sell to foreigners or to export. However, for coins extracted under the circumstances stated by the OP (i.e. during the 1950s), Western coin dealerships should have no fear: antiquities removed prior to 1970 are not covered by the
UNESCO Convention.
A final word of warning: be prepared to be told that not all the coins are genuine. "Selling fake ancient coins to foreigners" is a scam that has been running in the Middle East since before the Crusades. While selling genuine ancient coins to foreigners is a crime, selling fake ancient coins is perfectly legal, and they have no legal compulsion to tell the person buying them that they are fake. As a result, a random stranger in Turkey offering to sell ancient coins is quite likely to have been selling fakes.
