In his wonderful political novel The Possessed, Fyodor Dostoevsky wrote that socialists obsess about their own money more than anyone. Anecdotally, the flaming lesbian socialist professor whose office is next to mine is constantly on the phone with someone talking about her investments. (I can see why she worries. She has a lot more money than the rest of us. Her salary is 20 percent higher than any faculty I know.)
The General Social Survey asked respondents who is in charge of family finances (sample size = 208). This might not be the perfect measure of concern for money, but it's the best one I could find.
Twelve percent of liberals compared to 24 percent of conservatives said their spouse takes care of the money. (Gender is not a factor. Also--most couples share the responsibility.) So, by this measure, twice as many conservatives don't focus on money.
