The shape behind the menorah is the actual biblical borders of Israel promised in the Bible, not the tiny sliver it now controls. Israel has never yet controlled the entire border, indicating that the promise is a future one. The symbology of the menorah is from a miracle that God provided that indicates faith in God's promises.
This coin is effectively israels penny, it is ubiquitous, they build up in your pockets and it takes a pocket full to buy a coffee. Everyone has too many of them, including the Arab workers.
It is an in your face statement to the Jihadi that their genocidal call to drive the Israelis into the sea to drown will not only not happen, Israel Will soon expand to recover Syria, Lebanon and Jordan as God Promised.
Prayers for Israel.
