Deuteronomy 22:19

They are also to fine him a hundred shekels of silver and give them to the young woman’s father, because this man has given a virgin of Israel a bad name. And she shall remain his wife; he must not divorce her as long as he lives.

Note 100 shekels is approximately 2.5 pounds or 1.1 kilograms of silver.

They shall fine him one hundred shekels of silver, and give them to the father of the young lady, because he has given a bad name to a virgin of Israel. She shall be his wife. He may not put her away all his days.
