[Missionary in Sweden]

I have a friend who has committed a horrible and unmentionable immoral act and I'm wondering... for his sake... how much is 50 shekels of silver is in today's value?

I'm actually not sure this even applies since this lady is clearly not a virgin. So marrying her feels like it doesn't really apply? I'm a bit confused here, because even though she's not a virgin I still suspect my friend has committed a sin and should make some sort of penance.

...any help would be much appreciated.
