'Shekels of Silver' in the Bible

And they shall fine him a hundred shekels of silver, and give them to the father of the girl, because he has brought an evil name on a virgin of Israel. And she shall be his wife. He may not put her away all his days.

then the man who lay with her shall give to the girl's father fifty shekels of silver, and she shall be his wife. Because he has humbled her, he may not put her away all his days.
