Old money is wealth that has been passed down through generations. It usually comes with political influence and the knowing of powerful people. It is the type of money that people will pass down, and will probably last for many more generations. New money is money that has been acquired more recently. So for example, even though Bill Gate's kids didnt actually make their own money, and will inherit it when he dies, it is still new money because it is a relatively new acquisition. Also, new money tends not to last or stay in the family as long as families who come from old money.
Old money is a person who was born into a wealthy family, therefore will inherit that cash. New money is someone who had to build it up themselves, did not come from first class from the beginning.
