不能这么一概而论,而应该看情况.
如果是指金钱本身,应该是不可数的,就像我们常见的：
I have a lot of money.
He earns a lot of money by lottery.
如果指款项金钱总数,尤指某一特定性质的,则用复数.例如：
Indian moneys are defined in section 62 of the Indian Act as being either capital or revenue moneys.
印第安法案第62部分所定义的印第安资金抑或为资本,抑或为收益资金.
state tax moneys; monies set aside for research and development.
国家税收；为研究和开发所贮存的资金
