This coin was minted by a Israeli organization showing Donald Trump's Face on one side and the new Temple of Solomon on the other and it is being called, "The Temple Coin".
It also has King Cyrus next to trump who let Jews come back to Jerusalem from exile in Babylon.
It is to honor Trump for the 70th anniversary of Israel's creation as a state.
The coins will be 1000 of the 2 inch diameter coins and will be sold for 50$ each. They will be made of pewter and plated with 10 grams of silver but it won't be usable as currency.
