How much Spain money in the us worth?

It's variable, so any answer I give will be out of date by the time you read it. Your best bet is really google.

Assuming the "Spain money" you're talking about is the Euro, typing

1 EUR in USD

into the search field should get you an answer.

As of right now (as I'm typing this), 1 EUR = US $1.36. But, as I've mentioned, that could change, so you're better off checking for yourself.
