The latter is just blatantly incorrect to my mind.
Conditionals are an area where semi-literate people often trip up
Sadly I've heard constructions like that in speech fairly often.

And the former would usually be "If you had had some money, we could have gone to the movies", although I suppose it's acceptable as a mixed conditional.

"If you were to have some money, we could go to the movies."
That's very weird ... I've never looked into the "were to" construction. I mean obviously it's pretty rare in usage nowadays. In this case it looks very unnatural, I think it's because "were to" should be followed by an action (i.e. not a stative verb)
