Disgraced ex-Assemblyman Sheldon Silver could be scraping the bottom of the barrel next month to find the money he needs to pay the first installment of a $1.75 million fine imposed on him by a federal judge.

At his sentencing Tuesday, Manhattan federal Judge Valerie Caproni ordered the fallen power-broker to fork over $5.3 million in illegal profits on top of a $1.75 million fine.

But after factoring out his ill-gotten gains, the septuagenarian jailbird will have slightly more than $2 million left. That includes roughly $1 million in “liquid” assets and his stakes in the Silver family homes, sources told The Post.

Silver was sentenced Tuesday to 12 years in prison for taking millions in kickbacks.
