CHICAGO (WLS) -- The Illinois State Treasurer's Office is reminding people to cash unclaimed property or I-Cash checks.
Illinois Treasurer Michael Frerichs said the checks will arrive in the mail in coming days.
Checks went out to roughly 140,000 people as part of the latest round of the Enhanced Money Match program.
The program allows the State to return money from things like old bank accounts, or overpaid utility bills, without people having to file a claim.
The state treasurer said many people don't think the checks are real.
