Judas betrayed Jesus for "thirty pieces of silver" by pointing a kiss at the soldiers of High Priest Caiaphas, who then handed Jesus over to the soldiers of Pontius Pilate.
Although the Bible does not specify where the silver coins came from, based on texts of various prophets, researchers believe that they were probably Cheese shekels - currency of Tire, ancient city of Lebanon.
In the New Testament era, the shekel was worth about four drachmas or four dinars (the Roman coin). One coin weighed less than half an ounce of silver - almost 16 grams each - and its present value would be calculated from 400 to 500 dollars. Therefore, approximately , the 30 silver would be worth about today 12.000 dollars or 15.000 euro.
