The word lucre, in and around the 1400's meant money or riches, but pointed to it negatively. The filthy part in this expression points out to something that has been done unduly. At the time foul or filthy lucre were popular which eventually changed to 'filthy rich'.
In 1526, William Tindale used it in his work. In the 1900's the phrase came back and became more popular than it was originally. In 1929, an Ohio newspaper used the phrase to show the get rich quick attitudes that prevailed back then. Filthy rich is no longer used in just a negative way, it could be referring to the magnitude of richness too.
