This coin was once part of the Northern Sinai hoard, found around 1965 "at a tel just to the west of the village of esh-Sheikh
Zuweid. The site of the tel, on the ancient Via Maris, has been identified with the Beth Tappuah (i.e. House of the Apple), known
in Greek as Boutaphion. It is on the coast c. 15 km south-west of Rafah towards El Arish, which in 1965 was the capital of
Egyptian Sinai." (1)
The coin still has the original green patina which is typical of coins from the Northern Sinai Hoard..
