This small museum in the Federal Reserve Bank of Chicago is fun for a quick browse. The best exhibits include a giant glass cube stuffed with one million $1 bills (they weigh 2000lb) and a counterfeit display differentiating real bills from fakes. Learn why we call $1000 a "grand," understand how Alexander Hamilton created the USA's financial infrastructure and snap a sweet photo clutching the million-dollar-stuffed briefcase.
You’ll also get a free bag of shredded currency to take home. The museum is a school-group favorite. A 45-minute guided tour takes place at 1pm. When you enter the building, look for the "Money Museum" sign; you’ll have to show a photo ID and go through a metal detector.
